Just undid the changes handling normalisation of blocklists to improve matching of lookalike characters, as this was causing issues in multiple international groups.

I do still think this is a very helpful feature for fighting spam though! So if you would like to keep using those changes, this is now possible by using the lookalike prefix. Just use:
/blocklist lookalike:bot to stop users from sending messages containing things like bot, вот, or b0t.

Enjoy, and apologies to anyone who faced any issues with this.
