why do you consider it is worth discussing now when the project is long abandoned/passed and you cannot even recall what happened then?
Very simple. My best guess is, in the recent time you wanted to have an argument with him and somehow he felt it did not go the way he wanted. He tried everything to overturn your argument but failed. There are few members in the forum including JollyGood who are always chasing forum members to dig grave for others. I sometimes feel the forum is losing members because of these group. These so-called scam busters, forum police are doing everything to be sure that they stay in the DT and harass members.
You best guess is very correct. You are knowledgeable of the things happening in the DT.
The whole issue started in the John Abraham thread where I gave my opinion but some felt rby is nobody to speak on the matter. Read this statement
Yes bringing up the subject is a bit off-topic here (for now) but it is odd seeing accounts that barely frequents the Reputation board giving their unsolicited two cents on this particular topic.
I was actually giving my unsolicited opinion among BTT judges.
First, they tried to link rby to naim027 but to no avail;
They came up with the accusation that rby is a shitposter, and now they came up with speculative accusations without prove.
I can also recall where I disagreed with the accusation that Naim027 is also Royse777.
Royse777 ≈ Cratoon ≈ John Abraham ≈ naim027 now?

You really think I have time for signature spamming, account farming and all these shits?
Royse777 must be a superman or a bot for him to be naim027, John Abraham, AnotherAlt, cryptoSoul, Cratoon and one other account I can't remember it's name. It was used by naim027 for ban appeal. Someone who can farm these accounts is really someone who has no other things to do apart from posting and applying in signature campaigns and not someone like Royse777 who manages upto 5 different campaigns and also manage bounties and other services.
It is now I began to study the feedbacks left Royse777 and some other persons and I understood that there is a gang and if you belong nowhere and appear in the reputation board you may be taken down. No wonder people avoid reputation board and allow judgement in the hands of few.
I surely know that if a DT member delights in destroying people's account by leaving red tags without proves, even if nothing happens to them, the community is seeing. And they may not be on DT for so long (for ever).
