These sorts of posts that tend to be what the paid bumping services make. Just enough to make it look like a genuine question and not just fake spam but still a mostly hollow question that's sole purpose is to keep the thread at the top. Check their other posts and if they're all the same or similar report them and they'll be looked into. Often patterns can be spotted like same email address and sign up dates etc.
