Not only is this a way for you to keep your stuff, inform you what reddit knew about you and in general good to do with services you use every now and then - it also tends to be quite expensive operation for tech companies that aren’t quite operationally mature yet.
In other words, strongly recommend making a request if you still have an account.
There is a general lemmy world discussion board. Also a reddit one, which would probably be the most appropriate that I’ve seen so far.
Edit: c/general or c/reddit
