I requested my data the other day too. I haven't heard anything yet, which makes me wonder if they will actually do it, because I'm sure they got a ton of requests at this point. I'm hoping to get that before I pull the plug completely.
It's more like, how long is my patience, because I expect they have an unusually high number of data requests to sift through. I'm in the US, so I can't really claim GDPR anyway, right? Not that I know much about it in the first place.
What's the benefit in requesting your data? I tend to periodically nuke my Reddit accounts and cycle through usernames and I've never thought to save anything.
