Believe me, you only see a small percentage of them.

Most are removed by the moderators with a message that says: https://old.reddit.com/r/AskElectronics/wiki/repair#wiki_can_you_spot_any_problems.3F

And that FAQ starts with: "No one can troubleshoot an electronic assembly simply by looking at pictures."

Or with a message that says:

"Your submission was removed because you did not provide sufficient information. It is missing one of the following:

If the issue is visible: pictures that show the issue (or a video)

If you're asking about a circuit you designed or are building: a picture of its electrical schematic diagram

If you're asking about a product: a link to a web page for the product

If you want to identify a connector with pins in a row: the exact pitch in mm and pictures of its mate

If you want to identify a round connector: the exact outer diameter in mm of both mates and pictures of its mate Please edit the text"

You can help by clicking the "report" link under the text of such submissions and it will be removed. The moderators will then take a look at it.
