I don't have a single member or forum blocked. But I don't open many threads here cuz of lack of time or interest.
I do think there is a certain personality who feels the need to block rather than ignore posts or posters. Ducking for 🍅
ETA I'm not referring to blocking threads which can cause someone pain ie someone suffering from infertility blocking pregnancy and children threads.
Or maybe if you blocked all the forms you don't read you would not have anything to post on your favorite thread.
