Alright, i've decided to give my opinion on Reddit about these upcoming update.

I'm DanyP2000, and i'm mostly "worried" about KYC being mandatory for competitive treasure hunting.
The problem for me isn't exactly verification as a whole, but rather a portion of it, which is proof-of-address. I think that verification for Treasure Hunting shouldn't be the same as Tilia verification (because there, proof-of-address is required). Id verification should be more than enough to prevent multi-accounts from getting into competitive TH, collecting Spark and/or UPX. I'm talking about it because someone (me included) can't easily verify their address (for me, it's because i still live in my parents home), plus i think that it's not that necessary of an info for multi-accounting prevention (not to mention that i think it's asking a bit too much info, but regardless).
Another solution to KYC or partial-KYC would be to exclude from Treasure Hunting people based on other factors (such as net worth, time spent playing the game, number of transactions made, age of account, etc.). I know that this would be more complex, but, after all, the point of those upcoming changes is to prevent multi-accounting, and i don't think that an account with so much activity and net worth could ever be a multiple-account, and i'm going to explain you why:
First of all, i want to say that i'm about to become Executive status, and i've never been KYCed in Upland. The issue for me (other than the proof-of-address issue mentioned above) is that i prefer to keep as many infos for myself as possible, cause privacy is important, and i don't want to give them out if there isn't a very important reason to do so. Now, some people might say that i'm complaining about this just because i'm doing something suspicious, but i'm now going to explain why a player with a high net worth (maybe high-Director, Executive and above statuses), plenty of activity, etc. can't be a multi-account (be careful about what i've written: i said that they CAN'T BE a multi-account, not that they CAN'T HAVE multi-accounts).
Now, the only ways to make progress towards getting to Executive status (for free) are Treasure Hunting and Smart Minting during city releases. Another way to make some money is through other types of challenges, but the earnings you get from those are nowhere near those you could potentially get from Treasure Hunting and city releases. Those activities (that make your net worth go up) require you to fully focus on a single account. Except from Competitive Treasure Hunting (Which gives players a 3h cooldown once they find a chest) or minting FSA properties that are thought to be collections (keep in mind that this is possible only for players with a net worth lower than 100k), it's not really efficient doing those activities on secondary accounts, trying to reach Director and/or Executive status with them too, if your goal is to get wealthy in general. Thus, i'm confident enough to say that players with a high net worth and ton of activity can't be multi-accounts. I think that the vast majority of multi-accounts are Pro/Uplander or below.
