[Feature Request] Regular Expression for User Purging and Room Evacuations

[timaeos]

As mentioned in the #dendrite:matrix.org room:

Having a regular expression format that allows for mass user deletion / purging would be useful for managing spam account abuse. I would preferably want there to be a confirmation step that shows example accounts (<20) that are going to be purged or deleted prior to performing the purge because malformed RegEx mishaps are bound to happen.

Similarly, mass evacuations of rooms would be helpful for moderation.

oh hm i never would have thought about that. i kinda like that idea since many spambot scripts will do @spambot_[randomstring]:server.tld which could be reasonably picked up by regex. re: my confusion evident in #1

as for mass evacuations, assuming you dont mean evacuating multiple rooms at once that is already a natively supported admin endpoint and of course this will have it, see #1

im reopening, and im going to just make them distinct between the two issues
