There are folks on Bitcointalk who have 2,3,5,10 or even 15 accounts and more. There are many reasons to have a bunch of accounts, fun, propaganda, signature campaigns, schizophrenia &c., you name it.
This forum is very liberal. Do you supports the forum's decision to allow this practice?
If your goal of having multiple accounts is to do bad. You will get caught it all depends on your reason for multiple account's. And when you get to a point I honestly cannot find a reason for it.
The big red flag I see is you mention "signature campaigns" if you are using more then 1 account for this I think chances of leading into spam are very good. Espically if you use multiple. It leads to spam eventually I think for almost all that do it. And this leads to ban... which some think they can beat then leads to ban evasion. It's kinda a slippery sloap.
And Lauda is right on look a few threads down someone learned the hard way just sit a minimum bid don't use shill accounts to bid -
