All share the same IP, and have numerous transfers between them. I've witnessed them leave and join right after eachother (copied that part of the chatlog, although I don't know if that's credible). Also, 'Dragons_Fire' has the e-mail address 'blazedevil06@yahoo.com' (similar to the other CB account, 'Blazedevl11'). 'Blazedevl11' has the e-mail address 'blazedevil_da_best@yahoo.com'.
That's it, I believe.. Hope this helps.
Also, I'm not saying this is a case of (?)multi'ing!
