So, lemmy seems to be flooded with spam bot accounts at the moment. Look through the table of servers on fedidb (https://fedidb.org/software/lemmy) and notice how there are these huge instances without any active users (MAU).
Also notice how startrek.website has 9000 users for 276 active users this month.
From memory, when I signed up, there was no email requirement or captcha or anything.
Admins … maybe you want to tighten things up?
Sure, go for it.
Include a mention that even running queries against the database won’t necessarily be easy if you don’t know what you’re doing. where it is located and (separately) how best to access it will depend on how it was installed.
