At least Google and Twitter have data takeout.
I recently discovered that, on Reddit, anything beyond your more recent 1000 posts/comments/upvotes is totally irrecoverable to you, even via scraping.

Thank god I haven't made over 1000 comments or posts with any one account.
The data's all still in the database, but due to their caching setup, only the last 1000 of anything is publicly indexed. While everything's technically reachable, it's all deep web. To recover something private like upvoted or saved posts, we're talking heat-death-of-the-universe, through a full-table-scan squeezed through brute-forcing a search box, while authenticated, with rate limits.
