I don't know about that, I really don't.  I'm pretty sure a thread like the one OP linked to wouldn't show up on any Google result (at least not in the first few pages), there is a non-negligible chance that someone could find it and base their decision to visit 1xbit and deposit money there on it. 

I also think a negative trust is a bit harsh.  I have mixed feelings about tagging 1xbit campaign participants and won't do it personally, much less tagging someone voicing his opinion on that casino in a thread that asks for opinions.  That's being overzealous IMO....but JollyGood, I'll tell you: I won't complain for a minute if you keep the tag in place, because his idiotic opinion and that begging for bitcoin deem him a complete parasite in my eyes, and it'd be better if that negative trust inhibited him from joining sig campaigns/bounties in the future.

The trust system is yet again being used to control the shitposter/moron problem, just like it was prior to 2018.  I don't know if the merit system has lost effectiveness or what, but if it's not keeping the problem in check then I think we need a better solution than tagging members like this.  Anyway, I'm fine if you don't remove that feedback, JollyGood.
