The great thing about browser extensions is that you can customise the look and feel of the browser to your liking. You can turn HotCopper into a fanzone instead of a forum.
If you don't like downrampers or, for that matter, anyone who thinks that a stock that you own is worth as much as you do, or a CEO that you adore is as honest as a newborn babe, you can put them on ignore.
But wait, there's more. You can change HotCopper from a forum where things are discussed, to a fanzone, where only the positive is discussed. No negative vibes.
You can automatically increase the market cap by a factor of 10x, or even 100x, if you like.
You can include add-blocking, or even replace adds with adds for your own shares.
Make hot-copper your own - write your own browser extensions, or get a paid up-ramper to write one for your.
Or get a forum rat to do it - but you'll never know if you put them on ignore.
