One of the Puzzling Stack Exchange moderators, Rubio, has provided us with dataset of usernames which were used to spam Puzzling Stack Exchange.

The list is here https://pastebin.com/CkeV99c5

Can we come up with a new Regex list to catch most of these spammers?

I need some help to create the regex list, not to develop anything. We can use a new file on GH to store the new regexes and just use the same code which we are using to match against the smokey blacklisted username list.
