Warning for pasting into comment fields

As a Roblox developer, it is currently too hard to read comments effectively mostly due to chain-spam style comments. These kinds of comments are rarely moderated and encourage the reader to spread the same message to other items - here’s one example that’s floating around:

How to be cringe:
Say ninja
Dab slowly
Say fortnite
Hold your breath
Don't breathe until you post this on another item
Check your voice

If Roblox is able to address this issue, it would improve my development experience because chain-spam commenters won’t be so keen on monopolizing the space from those actually saying something about the item.

A straightforward fix would be to show a warning modal when the user inputs many characters at once (ie. paste) into the input field. A reminder that spam is against the rules would be highly effective in educating commenters about the dangers of posting it. Example:

Woa, hold up!

It looks like you pasted some text into your comment. Remember, copy-pasted messages are often considered spam, which is against the rules. Are you sure you want to write this in your comment?
:leftwards_arrow_with_hook: No, undo that (Default. Dialog closes and comment field reverts to previous content.)
:arrow_right_hook: Yes, keep text (Dialog closes. Comment field remains unaltered.)

The temptation might be strong to use existing tools to moderate phrases that encourage chain-spam commenting. For the purposes of this thread, let’s avoid entertaining ideas about dealing with chain-spam after it’s posted, rather than discussing ways to prevent it altogether.
