It's amazing how crappy the internet has gotten over the last decade or so. Yes, before that was the blogspam and link hijackers, but those were real problems that search engines were actively cracking down on via their Spam teams.
In the meantime, the relevance teams took a break and started trusting their social signals too much - now we've built an internet which incentivizes popularity over accuracy and has done so for a long time. Used to be that I could find things on Google and, if I couldn't, I knew the advanced search tools to tailor the search and get where I needed. Now, I just add "site:reddit.com" to the query. But if the niche communities die, that's a lot of knowledge that just vanishes.
Unfortunately many users have abandoned and deleted their accounts, rather than maintain control and authority over their posts.
So when reddit restores their comments, in spite of the fact this contradicts reddit's own terms and conditions as well as Californian and European law, users won't realise this.
I used the power delete suite to leave a nice explanation of Lemmy and ways how to migrate as well as a last happy fuck u/Spez on my main account.
My NSFW account has an even more elegant solution: Each and every post or link was edited to a highlight reel of the 2 girls 1 cup video, with no warning whatsoever.
Both accounts have been abandoned in this state, good luck restoring the OG content.
Although I suspect edits are less likely to be restored than edits+deletions, or even edits alone.
Certainly, I've had a couple comments that I manually edited that have stayed, while a few others have popped back up.
But so far, comments that I have edited and deleted from the source URL have stayed down. It's only the edits from the profile (using PowerDeleteSuite) where some have come back. Granted, most were old, now I'm getting info the recent ones they've been lingering on.
I still have a good 28,000 out of 76,000 lines to get through though from my original CSV file. I will make sure they're all processed before 1 July, and if reddit restores any of them I'll have logs to show their violation.
