A spam campaign to promote content hosted on divisare.com is currently under way. As of right now, there are 11 posts over 48 hours in the Metasmoke archive for spam posted on SE:
(I note that all of these are sites which are not subdomains under the stackexchange.com domain umbrella, though they are all members of the Stack Exchange network.)
The divisare.com site looks like it allows new users to upload random content (it's supposed to be about architecture, but the spam posts are unrelated to this topic), so I'm guessing what happened here is that spammers discovered this and are going unnoticed by the site's management (or maybe they noticed, but are not yet getting their shields up properly).
I'm creating this meta post mainly to have something to link to when sending a complaint to divisare.com, but to keep this nominally as a question, can somebody confirm or correct my observations so far?
