When a user (on a regular or a Meta site) gets a particularly high number of downvotes, it seems an automatic filter kicks in which bans them from asking any more questions, with the message:
Sorry, we are no longer accepting questions from this account. See [here] to learn more.
This makes sense for regular sites, as many downvotes would generally indicate particularly bad questions, potentially 'poisoning' the site and reducing its quality. However, for Meta sites, the downvote is used to indicate mere disagreement with a question asked. Surely it doesn't make sense to ban a user because they asked several (appropriate) questions, or made several (appropriate) proposals, with which many people disagreed? Shouldn't this auto-filter be disabled for Meta sites?
