I'm still awaiting the spamming of my Deviant art, tony, <3.
I am wondering who is telling bronys to spam you, though.
As much as i dislike you, I wouldn't go and spam you.
i've checked the accounts of the few people doing (or did) the spamming, most of them appear to be random trolls, some connected to trolling steam groups and etc.
out of all the ones I checked, only one was connected to the Blockland via Blocklanders steam group.
(an unimportant note: most of them are part of stupid steam groups about "love and tolerance", the irony is amusing and not unexpected. what a bunch of morons.)
so really, either that one person somehow got a group of idiots to spam a steam group and its creator, or a trolling steam group found it and decided to bombard it (one of tony's announcements mentions /mlp/, also a possibility). I'd say the chances of it being a Blocklander or someone from this topic are slim (there aren't even 20 topic goers that i'm aware of, much less 70), but that guess is only from the angles given.
if Steam allows you to report user profiles, I'd do that.
