If i decide to get on wifi using pokemon platinum rom...

is there any way for nintendo to know that it is a rom to block me or do anything?and does anyone know what they do to check if they check at all.has anyone else gone on the wifi using a rom of platinum, pearl or diamond?

For some reason I have been blocked from playing Tetris online recently; it could be a bug or even a piracy measure. Diamond and Pearl work online with no problems however. Just give it a go, the worst they can do is block you.
