My list since I've been playing cluedo on PM.
LittleTom or SUG. I was going to say So Instinct, groovey or Yaboy but they've all been denied by the user and the guy is using london/misc slang so it's not groovey.
In that order is who I think it is. I'd say little tom as he hasn't posted too much recently.
SUG is too hung up on a hoe to be trying to make a dupe I feel, but he is the other option if it isn't tommy boy, as he's said that he's made a dupe that nobody knows..
I also think that it's tom because of how his disappearance from parring him with his legs coincided with this guy coming in.
I'd also add that he said to Yaboy 'on average how many accounts do you make a day?' Meaning that he doesn't make many dupe accounts, however I know that he has had another account. But then SUG has said he has a dupe nobody knows of.
So I've narrowed it down to two people. You guys can vote.
Tl;dr. It's one of Little tom or SUG.
