i know mods have a lot on their hands and that this is a thankless job, but if many feel that the negative posts are no longer constructive, incessantly whiny, and often goes off tangent, maybe it's time for a different approach.
on some subreddits, mods require anyone asking questions or posting issues to post in a specific format (what is the issue, when did it start, software number, what have you tried so far, timeline/chronology of contacting lucid support, etc). the goal is to provide an outline for the complaint, trouble, issues, etc, so that everything stays on topic, provides a clear explanation of what's going on without missing details, and allows a certain level of barrier of entry for trolls.
after the posting, there is frequently an automod that directs the poster to FAQ sections, specific topic megathreads, official links, etc.
i personally still read the complaint threads, but if the OPs don't provide clear information, spends more time venting their emotion rather than the issue at hand, reeks of entitlement, and refuses to follow up with information that will help with diagnostics, i just assume it's a troll and aren't asking in good faith, and move onto the next thread. hopefully by having a strict form/guideline for posting their experiences, issues, and troubles, it'll guide the discussions in the right direction and make everything more constructive, for both parties.
