dear forum members,
from a technical view: to implement a mute/hide option would dig deeply into the forum code - it affects not only displaying posts, but also topics, new posts indicators, last post in thread indicators, tags, ect. would that really be worth the effort? shouldn't we waste our time on features which add some advantages to the website?
from a personal view: it has already been mentioned this is a liberal forum and the vast majority of posts are well thought-out and interesting, so moderators can stay in the background. we don't want the intonation in the VSL forum to turn into something we eventually find in certain social media groups.
i'd assume everybody here is respectful and tolerant enough that we don't need to have tools to exclude someone from communication. maybe it's actually just the summerly heat ...
and remember: only a CRAY can run an endless loop in just three seconds.
