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.
I made a request last weekend and never got an answer. Checking back today it say's I can't request again. Either they are way behind or they aren't giving out the info.
The people downvoting you are shortsighted. This place is for discussion pertaining to lemmy.world. There is a general lemmy world discussion board. Also the one for reddit.
For former redditors who can't seem to grasp this simple concept.. would you like you see a video of an alligator eating a pet dog stay on r/WTF, or would you like that content misposted in r/awww or r/EyeBleach?
We have specific places for specific topics for a reason. This is not directed at OP, but people who are butthurt for OP and being unhealthy users for the community.
Downvote because something is off-topic, trolling, spam, or hate. Not because you disagree or don't like an opinion. Conversely, upvote relevant content/discussion, not simply things you like. They're not supposed to be dis/agreement buttons.
