Is there a way for mods to yank a large number of questions all at once without deleting a user?
Moderators can click on the
delete button of many questions in quick succession. Not too quick or they get a captcha (I assume — I remember getting captcha'ed a couple of times when I closed ~80 questions in a row (commenting on each one)). There's probably a limit, but I haven't heard of anyone hitting it.
If you're worried about a moderator going on a rampage and deleting good posts: that would be noticed pretty quickly, and the moderator's account would be suspended.
If you're worried about a high-reputation user going on a rampage: the account would be suspended, and anyway there's a limit on the rate at which users can post questions (and answers, and edits… pretty much everything on Stack Exchange is rate-limited).
I was thinking of being an ass to prove a point
I was thinking about posting a ton of questions at the limit to show why a subset of questions is bad.
I highly suggest you don't. Making us mods busier to fulfill your desire to make an argument is not a particularly great idea, or effective use of your or our time. Make your arguments here on meta about the badness of these questions. And if the community disagrees with you, then accept it and move on.
If you want to spend time improving your arguments, then I recommend making them more effective via data, which always helps bolster posts requesting changes in policy. You can do this via asking for help on meta or in chat for help with making Data Explorer queries. Chat and meta are also great places to get the opinions of others in the community, and to discuss/debate their reasons behind those opinions.
If you need to fake-post a large swath of questions to prove that a certain type of question is bad in large numbers - it means that this type of question is NOT posted in large enough numbers to create a real problem, so you're worrying over nothing.
Moreover, "this type of question is a bad one because there are too many of the type can be asked" is clearly and demonstrably NOT considered a valid argument against a type of question, as evidenced by on-topicness of Story-Identification questions which are a poster child for "infinite pool of largely useless and potentially swamping things to post, many of which are prone to tons of unpickable answers" and yet the community strongly favors them being ontopic since they don't do any actual harm.
The best way to improve the site is to post great content of your own, not crusade against what you persieve as potentially bad content.
I may totally hate story-ID questions, but since the community saw fit that they are acceptable, I don't go around downvoting every single one of them, posting inane story-id questions to show that they can easily be abused, or otherwise harrassing people who post such questions.
There is a good article at http://en.wikipedia.org/wiki/Wikipedia:DDWIP on alternatives choices for proving a point.
Although I am not positive that the rule carries over, according to Is there a limit on how many questions I can ask?
A user may ask only...
- 50 questions over any 30-day period
- six questions over any 24-hour period
- one question over any 30-second period
- users with less than 125 reputation can only post questions every 20 minutes
If the rule does carry over, it would not be possible to add a large swath of questions.
