We, kia2 win, do get the occasional obvious bot posts often posting to gambling sites. It's trivial for a bot to make accounts and post but that they show up here at all means someone's analytics show this site to be worth the effort. And if someone running gambling bots has that data you can be sure much larger groups do as well.

And like Arch mentioned they are on .win in general so there is likely blanket coverage for these sites. "Stormfag" is even likely to be a treated as a keyword for bots (or humans) to monitor, the same way /pol/ believes "sneed" is now used.
