To install a necessary and useful utility found on most other forums called the "ignore user" feature on this board, I did ask this question in another thread the other day, but didn't receive an answer, hopefully this is the right place to post this suggestion

Such software exists. I've seen it being used. Sounds great in theory but in everyday use it doesn't work well.
Suppose you want to ignore user A.
Users B, C, ....., Z discuss with A so you still see the conversation and quite often also the text quoted from user A.
Say the next user that reads this thread has you on his/her ignore list.
He/she won't see your message but he/she does see my quote of your message.
Unless I'm blacklisted too offcourse
