I think not.
Cause a friend of mine sent some hacked pokemon from his GBA ruby
version to his Pearl version (via Pal Park) and they worked like normal ones in Pearl, he can even trade and battle wi-fi with them. (The Mew he´s using still have it´s japanese name, with japanes leters XD)
So I think that Diamond and Pearl don´t filter anything at all...
UNLESS if the pokemon´s stats limits aren´t broken, like a Caterpie with 999 of HP.
And, if Diamond and Pearl don´t filter hacked pokemon, probably the same goes to PBR too.
