Sorry to bring more bad news, but I've found the following spammer spamming this very same thingy. He is member-ranked so that's why he most likely got away with it:

Ah, see I wasn't sure if this was public knowledge, and that's why I was alluding to it rather than outright saying it. I thought I remember a discussion about MindlessElectron before, but wasn't sure if it was in Meta or not, and didn't have the time to check.

Good, I can go back to my tea now.

Maybe its possible that the Bot from Mitchell or from any other User that using one can catch them !
The easiest way would be Mitchells one as they get instant deleted with it , other only reporting them but thats also good.
If the Accounts new created and Newbies that are spamming there all other Moderators can deal with them also if they have the time for .
