You don’t need to DELETE all your comments, you can edit them all. I used the PowerDeleteSuite. Set the options to delete my posts, but not delete my comments. I then had it edit my comments with a paragraph about Lemmy and moving to it.
This is a great way to advertise Lemmy, over the long term.
So far it’s at a staggering 7500 comments edited. All advertising Lemmy.
So that’s an option. Then it’s done and reddit is behind me. Lemmy all the way.
I hope this helps
There is a feature to not edit comments that have more than X upvotes. So in theory, most useful information should be upvoted more than the rest.
