With the recent massive burndown of the close vote queue I've found myself banned from flagging despite having a very high flag acceptance rate. Given that the burndown is NOT a normal thing. Shouldn't we temporarily disable the hellban queue until the burndown is finished? I'm willing to wait out the ban but it doesn't seem logical for a large number of users who are trying to contribute to the moderation of the site to be punished all at once. That seems counter to SOs user moderated credo.
At this point, it doesn't matter: after 18 hours, you're no longer flag-banned. But my advice in any case would've been:
you might want to spend a bit of time figuring out why - maybe your flags were perfectly appropriate when you raised them but the situation changed by the time they were handled... Or maybe you're flagging things that aren't really problematic.
Remember, the instigation for the recent change to flag-bans was to make them temporary: you should never be blocked for more than a week at a time, and generally it'll be less than that. Treat it as an opportunity to learn.
As for the close queue burndown: that's actually why you were briefly banned! 10 of the posts you flagged for closure were reviewed in the past week, and 3 of those flags were declined. Note that each of these required the attention of at least 3 reviewers, attention that could've been better directed elsewhere - so again, try to learn from these so that you can improve the accuracy of your flagging going forward. Ultimately, this improved accuracy helps a lot more than having more pile-on flags.
