Read and Wait to see
Flarum is a discussion board and not a "thanks" "thanks sir" "thank you for this content sir" platform. But after running a website for a few months that's what I get when I turn on the "Reply to see" extension. People don't read anything and straight away go to the bottom of the page to reply with a big "thank you ". also many important posts get lost in these spam replies.
So there should be an extension that would let the website owner set a default minute value for all the discussion threads, before unhiding the hidden content. OR Even better, it should automatically figure out how many minutes it would require to read a discussion and then unhide the hidden content
That being said, I also don't want it to be like those referral sites where you have to wait 10 seconds to reveal a download link
