I think I heard psp say somewhere he didn't mind language-based fanclubs.
Though of course don't speak Spanish orso in a thread where everybody is speaking English, just so those people won't understand you. There have been a few threads like a 'Spanish Speakers', and they shouldn't get much trouble unless people just start speaking English and let just everybody come in and chat.
And 'Te amo' posting is still spam no matter the language. :x
