Fun fact, Reddit only soft deletes your comments. So all those people using Reddit deletion/comment mangling services to protest only deprive their fellow users of their insights. Reddit Inc. can still sell your data.
It makes reddit less valuable as a source of info.
I already click on reddit search results less after hitting now-dead search results a bunch of times.
That's less views and less mindshare.
Reddit will restore your comments even if you replace them with lorem ipsum with a script.
