I'm not happy with H239. The user (who is blocked on three projects) is getting subscribed to almost every Wikidata task and every task created by various people (including me), I feel stalked. I don't see any contribution factor in this Herald rule, I think it should be disabled. The user is already doing dubious stuff on Phabricator, including adjusting priority despite being asked multiple times not to do that.
The nice thing about the rule is that it brings random tickets back to the top of the pile .. The only problem is that on some days there are hundreds.
The user could probably have done the same by subscribing to the Wikidata project.
