Can facebook & twitter connect the dots?

If I have multiple accounts in each social network, but I keep making updates and tweets with links to the same blog from all accounts, will facebook and twitter be able to find out I have all those accounts and start banning them?

Sorry, need to bump

Well.. If I was a BHer who owned Facebook (which IS owned by a BHer), I would probably have it setup so that if one account was doing something and we caught it.. I would run a check on the domain being promoted to weed out any others.

That's just what I would do.

Twitter already similarly checks URLs in posts, even of legit accounts.
