Hm...I'm not so sure unfortunately. One of the fuckers at least, is a member of that forum. And I'm pretty sure it isn't a joke. Or at least, isn't a hoax. Seems like a fucking joke to them though . And they should have a good idea about the response they'd get, too, because I've let people have it from both barrels before for a lot less disrespect towards those with special needs or MR than that.
Tne 'gibberings' threads themselves, (there is a series, they change title once one gets so long it starts to bugger about with the database) are generally people about casually in the EADD subforum. But I don't think, given the specific poster, that this is a hoax.
In any case, I'm busily raising the mob with the pitchforks and flaming torches, to hound them out, and turn them into a despised pariah.
So they should have thought much better of it, than to do something so fucking stupid as talk shit like that..
