yes you can, you can get an GUID ban.
Title says it all really, apologies if this is a really nooby question

Probably not from PunkBuster servers.
You can get banned from non-PB servers I guess, if you go overboard with the hacks, but not the instant you go in with a detected hack.
i got guid ban yesterday, and i played with a hack for a week ago and yesterday i got banned =)
You'll get a GUID ban if someone reports you to DICE. But, you'll only get banned from the server itself not from Origin or BF3 if the admin bans you.
