@metasmoke @Yatin heads-up on sneaky spammers like this one: a watch on the domain (reported as "Potentially bad keyword in body" matching on the domain) usually warrants a second look (generally checking the
domain history), as it means the domain has appeared in suspicious content previously. In this case, about 20 "questions" linking that domain with keywords on the links like that, including a previous use of that username.
