A daily checkin type thread is considered a "public" thread, and the guidelines do state they should be started either by someone with no ignore list, or a moderator. So this should NEVER be a problem.

A private type thread is still up to the users discretion, as far as i know, where a person is asking for support etc.

Personally, i find somebody having me on their ignore list, stops me from crawling up their butt all the time. I may feel i like them and am being helpful, but if they dont feel the same way and they find me irritating, why should PC hold my words out there somewhere pointed directedly towards them? What a nightmare!

There are LOTS of other people to engage with on PC as there are in life, and that is a lesson in itself.
