Mine only had about 2,500 karma, and only five years old, but I deleted it, and now I'm here on Lemmy!
Should hold off on deleted your account for the time being. Many subs are polling users on which direction to take and I've been messaging mods with short comments to move to lemmy.
Don't forget to ask all your data under gdpr before wiping the account. I asked my data and after 2 weeks still it's not done so i have the feeling it's computationally expensive for them. So, the more users ask for data, the better
I used PowerDelete to replace my comments with Random Garbage, but it looks like only about 10% of comments actually got edited.
I've found that some subs are blocking mass edits and categorizing it as spamming.
Interleave it with edits in other subs over a period of time and change the message a bit each time so it's less detectable by scripts.
Wish I knew about shreddit or equivalents before checking out. Deleted my account, but years and years and thousands of karma worth of helpful content remains. Nowhere near as much as some of you guys -- but still years of thought and interaction and appreciated memes.
Much of the content I followed on reddit is now being posted in the fediverse as well. I'm very hopeful. Either way, not returning to Reddit no matter what. They are Digg to me.
I can understand a decision like this.
10 years, 184k karma. I'm blanking out my account sometime around the first (whenever I get away with it), and un-subbing from everything. I'll keep the account to make sure it stays empty, and to communicate with the handful of friends I've made on there who are probably staying on Reddit, but that's it.
