Yo Bro SirDennis, perhaps you can get the moderator to delete this thread immediately bro.
Anyway, it's no big deal if someone has a couple of nicks in SB. As long as the bro has not used them to cheat and decieve (write several fake FRs), sabotage (write false but damaging FRs to discredit someone) or destroy (gang zap), it's really not an issue.
Moreover, there are many reasons for bros to have more than one nick. I admit I do have another, because OC found out about my original nick so I created a new one to continue my fun here.

As for signing off with same "intro" name, it's not necessarily incrminating bro. I for one have done that when I was helping a TS with distributing a FL's contact. It's easier for the FL to remember.
Anyway peace
