I saw at some point some users who just try to identify spammers and people that are just copy paste content (so for not original content).

I can't remember that names unfortunately.
Maybe it will be good to have that people who do good to be in a list somewhere where we can report such cases.

I think next time when i will find one i will put a bookmark.

As i said in another post regarding that problem, that's the problem with totally decentralized platform.
For this abuses people must have the power to resist to such cases and go on. But with lot of spammers doing that i don't know who will resist forever.

Maybe things like that are reaching the devs and it can be a solution at least for slowing down that accounts... :-(
