It's getting a bit ridiculous now. Are you sure anyone is doing anything about this? It seems as if "hiring" a couple of mods to delete is about as far as it's going. To add a couple of features to prevent this sort of spam would take a few mins tops. Me thinks it be down on the list very unimportant things to do.
To be fair to the Larian chaps, they've had a long period of late nights to get the game out there (hoping not to sound too fangirly about it!) so their break was well-deserved. They'll get to forum manglement when time allows.
In the meantime, other volunteers and myself will nuke any spam we see. With any luck, before anyone else is plagued by it, but we need to eat and sleep too.
