Undo's advice is pretty spot on. Who can handle spam on Bitcoin? The site's community! For example, that's what happened to this question.
That said, when there's a wave of spam coming in like this, it can be helpful for us (the community team) to step in and set up additional measures like URL blacklists. In this case, I blacklisted
emocoe.com, so there should be no more spam coming in that mentions that domain. This won't necessarily stop someone from using URL shorteners or other ways to obfuscate the link, but it's usually a good enough roadblock to curb the abuse.
Having examined the mods' activity records, I think we should be okay for now. This looks like an isolated burst of spam. However, if the moderators aren't keeping up with the workload on the site, we can look into appointing additional moderators. After all, they're all volunteers and we can't expect them to be around 24/7.
You might also want to start a discussion on Bitcoin Meta to round up and educate more users about spam flagging and maintaining the site going forward.
Please do let us know (email
firstname.lastname@example.org) if you keeps getting waves of spam that don't get addressed quickly enough despite the community's best efforts and we'll see what else we can do.
