The app is follow-based, not WoT based. Follows take the priority. Everybody else has the same weight.

You're always talking about your users. Don't you care that your search does nothing at all to help them differentiate between real people and scammers?
I am. But the search puts follows up top with a following icon in each picture to make sure they know what is real.
We will add Follows of Follows at some point. But that won't solve the issue since WoT can be gamed and based on how well people are keeping their relay lists, I doubt follow lists are super clean anyway.
If your wot calculation depends on no false positives, it won't work, sure. Set a threshold, incorporate mutes/reports, show a number, etc. Lots of ways to improve the most naive version.
Lots of ways to game the WoT score as well. Especially with leaked keys from real humans becoming very common. There will be a market for WoT keys that can be changed to impersonate somebody else.
Yes, everything can be gamed, in theory. In practise the game can also be cheap to play for the defender, and expensive for the attacker. The game also does not have to be static.
