Current thinking is that the max allowed Ignore duration will be 4 months, after that it auto-clears and you’ll need to explicitly renew the Ignore for it to keep going. No change to Mutes, those will have unlimited time duration, as before.
Totally legit concern, so we are making Ignore a trust level 2 ability that you must earn by achieving TL2. Mute is also being moved to a TL1 ability. Details on trust levels.
