I left negative trust for all 3 sock-puppet scammer accounts posting there. I mean, they all seem so happy to have been scammed 
So if 50-100 people post about them getting their funds and 0 post about not getting them are you going to tag every single one of them as an alt of me (even though you can clearly see they are not mine)?
If all 50-100 were newbies with 0 or almost 0 post history, probably.
If many of the 50-100 were users with a history on the forum, I don't think it would be fair to tag them all.
The three accounts I left negative trust for have a post count of just 3,2 and 1 posts.
There is a total of 6 posts between 3 users who amazingly found their way to the self-moderated thread that serial scammer Dean Nolan created: https://bitcointalk.org/index.php?topic=5201753.0
