I got a few posts from them in the communities I moderate, it might be good to keep an eye out for them till they go away / are banned. There are a handful of accounts either posting the links or pretending to be happy buyers.
I don’t think anyone will fall for it, but some links are sticking around because the community mods haven’t noticed (or they did, but I didn’t notice because I got to those posts through the links).

OfficialPartner is another one. I had them and softwaresales posting spam in one of my communities.
