Hmm, I have 1/4 TB worth of toots going back about a year on my single-user #selfhosted #vernissage instance. Why is the bit bucket so full of bits?
Aha, I neglected to enable the purge old toots job.
Source code seems to say it'll leave local toots and any remotes that got some interaction alone, so ... seat belts off, set it to 30 days retention.
Annndddd... go!
