Uh, huh.
So why start this thread at all? I like to investigate with other members and get their input, then take it to the mods. If i ran to a mod everytime i suspected someone you'd grow tired of it and not take into account any further messages. This will help you by not being bogged down everytime theres something suspicious, we members don't mind doing a little detective work, what you are asking is to take that away from us. Why not simply report your suspicions to the people who actually have access to information and tools that would be able to make a concrete connection? If the link is there, it would be dealt with. You can't always put it together with a link, some are smarter than that. If not, you see no change.
All without stepping up on your soapbox with a bullhorn and saying...what have you said here again? Oh, right, you didn't name anyone. Ahhh...some i'm not wrong, i just can't find the hard evidence, yet. Saves on embarassment when you're wrong that way.
Food for thought. If failure to capitalize were solid proof of multiple accounts that would mean one user had several thousand accounts, yours included.
