Why not an extension that makes the "save" button cancel instead?
How can you put effort writing a comment if you know it will be deleted before people read it? How can you bear to keep your deleter enabled after you just posted a comment you thought interesting?
And quite frankly, how do you justify going into other people's threads and littering them with useless "[deleted]" comments on purpose?
So you get value from the community, and leave a trail of confusing deleted comments for the others? What experience remains if everyone would do the same - Kant's "categorical imperative" would imply this is unethical.
If deleting my comments makes reddit painful to use then it hurts reddit in the end... But it seems to be affecting you on a personal level so I'll start doing it more now
