If you're putting PII on a random forum, that's your problem, respectfully. I have a specific email account for "random forums" and don't put real info in my account.

I disagree that random forums are spam-fests. That is purely a matter of moderation and user activity. Overclock.net and bronco6g.com are two (non-reddit) forums I can think of that I've been to recently, and neither have a large amount of spam posts.

You can set up email notifications to thread replies in most forum software, so you don't have to actively check if you don't want to.

Finally, I reject the notion that you can effectively search through years and years of discord or slack chat for topics related to your question. The nature of creating a thread differentiates itself from a "random" post. Perhaps if Discord/Slack's UI prompted a person to label a post "conversation starter" or "thread starter" then it would be better organized.
