Very true. The fact that BSV is discussed, and their thread gets replies regularly is good for their exposure. That's all that really matters, not the content of the discussion. Any attention generated here is good for them.
As for banning the troll, it would be more peaceful around here if we could definitively connect all trolls to banned accounts.
The ANN thread for BSV was created in August 2018 were using fake conversations are very useful to bump the thread up that is why they create a lot of accounts just to do a fake conversation in that thread. Simply they are hoping for that bumps they have in the past can translate to more views for their thread. Bitcoin SV on the other hand cannot be banned for trolling in the forum even if they are spreading false news against Bitcoin itself, so really the only way to permaban this account is to connect them to korner or one of the 50 accounts connected to him and be banned for ban evasion. But from the looks of it OP really doesn't have any concrete evidence to ban Bitcoin SV since there is no direct connection from what he have said since he only connected Bitcoin SV and korner to some kind of habits they have in the forum that are very similar and it would take a whole lot more for them to be directly associated to one another like using the same address, posting the same contact info or anything that can connect them as one person.
