Out of curiosity, why? The amount of times I’ve banged out a Reddit or hn response and deleted it is almost uncountable. Why do you bother replying to Reddit comments?
Deleting a comment doesn't delete it from reddit's backend, only from public view, so reddit still retains and can track and sell your data. Making multiple accounts (assuming one also takes other steps like using a VPN and clearing cookies and local storage) would make it harder for reddit to connect all your comments and build a profile on you.
That's why people were using extensions to edit their comments to random words instead. Apparently Reddit had no way to un-edit a comment. It's probably been fixed by now though.
They didn't even say they reply to anything. Perhaps they use it entirely to post local news stories.
Unless you have a reliable social network with reach, reddit is still the reliable way to get some answers for one niche or another.
"A", not "the".
Your behavior is even stranger than that which you are questioning. The fact you take the time to type out the response means you also feel the urge to respond, and that urge is strong enough that you don't stop yourself before starting, even though you know you are likely to just delete before sending. It's odd that you would ask why someone would reply to a comment when you should already understand why someone would do that: because they feel the same urge you do, and don't have the compulsion to stop themselves before sending.
It’s therapeutic. Try it sometime
I've done it. I don't agree that it's therapeutic.
