en.wikipedia.org and others have seen a rash of abuse coming via Tor in the form of account creations with abusive names and such; this is taking up a large chunk of CheckUser and oversighter time and effort, which is apparently not too fun.
It looks like the current settings don't generally restrict various actions to a logged-in user when accessing through Tor; is there any objection to tightening this up to restrict edits, account creations, etc via Tor except when the account is explicitly excepted?
