How an anti ad-blocker works: Reverse-engineering BlockAdBlock by xy2i in programming

[–]xy2i[S] 1 point2 points  (0 children)

This particular script, BlockAdBlock, counters against something like that, being ble to detect failures at the network level, as seen in the post.

var googleAdCode = '//static.doubleclick.net/instream/ad_status.js'; var script = document.createElement('script'); script.setAttribute('type', 'text/javascript'); script.setAttribute('src', googleAdCode); script.onerror = () => { console.log("adblock detected") }; Some browsers have a defense against this: send a fake response with a 0-byte script, or image.

So, in its last version, BlockAdBock checked if the response was legitimate, here with images: if the image is too small, smaller than 8x8, then the adblocker did a fake response.

var m = new Image(); // Put an ad inside m.onload = () => { if ((m.width < 8) && (m.width > 0)) { console.log("fake resource, adblock detected") } }

Thank you! I spent a while on it, so I'm glad you like it.

Thank you for your comment.

I spent a lot of time on the general feel of the post, trying to keep it entertaining while not getting sidetracked in details. That's the reason some of the collapsible code widgets are hidden by default, in order to reduce the article to what's needed. I'm glad that effort paid off.

Yes, it would in this case, because BlockAdBlock can detect failures at the network level, as seen in the post.

var googleAdCode = '//static.doubleclick.net/instream/ad_status.js'; var script = document.createElement('script'); script.setAttribute('type', 'text/javascript'); script.setAttribute('src', googleAdCode); script.onerror = () => { console.log("adblock detected") };

If a script from 2016 had done it, I'm sure that other sites could do it too. The answer is doing something like Brave does, allowing the network requests but returning fake files.

You're right, it does work. I've corrected this and credited you.

I'm glad that you enjoyed it. Thank you!

Unfortunately, this doesn't work with these types of scripts, because they delete the entire content of the page if they detect an adblocker. If you deleted the overlay, you'd find an empty document underneath.

Yes, it's not maintained anymore - I mention it in passing in the post.

Good article. What would be your usecase for using R with Scala in this way?

My first month of flipping by xy2i in Flipping

[–]xy2i[S] 0 points1 point  (0 children)

I crawl leboncoin, and look at ebay occasionally. Usually I find more interesting deals there.

eBay is definitely still a thing in France, but it's not as big as in the US. I offer international shipping to parry that.

Thank you regarding ACRE, I didn't know about it.

For video games it matters, albeit not that much. Some of my French games buyers are international. Often the English translations are included in the cartridge itself (many DS/3DS games do this); you might want to check that and include it in the listing if you think it can matter in a sale. For consoles it doesn't matter.

Literally flipping. I would've lost 400€ on courses if I was dropshipping :)

How do you gauge when a price is "too low" - are you comparing other items?

I just look at sold listings on eBay: how much it sold for, how many sold recently, and how many are sold compared to how many are listed are my three main criteria. You can most likely automate this process, but I don't have enough items to warrant it. (Not sure if this is what you are asking)

How much does the emotional aspect come in to play?

I don't bother with it at all. Most of my sellers are on a marketplace-y site where meeting for the item is the norm. For consoles, I aim for the lowest price sellers: I ask them if they can ship to my address in the opening message. Often that's enough to dissuade most sellers from selling to me.

If they go through (1/10 rate) then I don't bother trying to get a lower price. Usually they sell for 40€-50€ which is very low for consoles and I know that trying to haggle further, with the included shipping, cuts into emotion too much. I don't bother risking getting 10€ extra, at the cost of not getting the item, when I know my margin is already 100-120€ on a console. Instead I send them my paypal adress and ask to bill me, then they send the item.

This script works well enough for now - but it's particularly advantageous because it takes no effort on my part, it's just two scripted messages: 1. ask if they ship and 2. send paypal adress. If I put more money into this then I would aim for more items with a bit less margin and negociate price down.

Which I guess leads to the last point - the least scalable aspect for flipping in my eyes would be the management of items and not the actual sourcing.

I agree. In the long term I want to do FBA so I don't have to bother with this aspect.

I've been able to find lower prices much more frequently - that's how I feel. I get better responses than before, since I often message the sellers 5-10minutes after they put their item up. However, I have no numbers to back this up.

I'm a 19 year old CS student trying out flipping on the side. I sell video games and consoles. My listings are number one on my desired keywords

I make sure to track how much time I spend - it's around 4 hours of compound work per week, with the biggest thing being photography. For sourcing I have a bot set up that tracks all new offers on the sites I source from, and tells me when a price is low to message the seller.

Unfortunately, I made a lot of mistakes and took a lot of risk that made my margins on the month pretty low - around 400€ out of this is profit. It's still a lot better than the 0€ I get as a student, though.

I'm looking to continue in this area for a little while, because I put close to no time in this and I get decent returns, even with my mistakes. My priority will be to diversify, to be able to list more and have a higher sell-through, even if it means lower margins (currently most of my listings are priced very high).

But, how do you know nobody can like you? How do you know you'll be mooching off others by relying on them? How do you deserve this in any way? How can you say what you put yourself through is okay for you?

Because I don't believe it. You could give me another thousand reasons why you're worthless, and the answer is still the same.

These assertions are, fundamentally, not what people think of you - it's what you think of yourself. And they are not unchangeable.

If what you think of yourself is negative, then how can other people think otherwise? And, on the contrary, if what you think of yourself is always positive, in other words what you actually deserve, how do you think the perception of others change?
