This is a lie. You were aware of scam accusations about betcoin.ag back in March:
No. I replied once and the thread died pretty quickly afterwards. I obviously memorize every single thread that I have ever responded to. 
Prior to receiving this public pressure, you make it well known that checking if betcoin.ag is shady/a scam was very low on your priority list after you started advertising for them.
It was on low priority as they did not have negative trust at the time, because I have better things to do unlike some escrow scammers. What am I missing here? I admit it's late in the day and me eyes is tired, but 1) I don't see a threat and 2) I don't see negative feedback by Lutpin on OP.
I had no idea betcoin was in trouble either, but I'm not in their sig campaign and I've never used their service and I don't even follow crypto news much. If they're proven, or even highly suspected to be scamming then I'd say people should be given warning to remove the signature if that's the issue. Some of the campaigners might be ignorant of the facts and not intentionally promoting a scam.
If you plan to get 'into it' then you've got a lot of reading to do. The accusations against the website in question have started a few months back (possibly earlier) and it wasn't until July that they've received negative trust (from several DT members).
