FediDB, Fediverse Network Statistics

FediDB is a cutting-edge service providing detailed statistics and insights into the Fediverse network.

Some small instances are seeing sudden increases in numbers of registered users (4k to 5k new users) but not an equivalent growth in activity, my guess is someone is creating accounts on instances without captcha enabled for account registration. Most of the top 10 fastest growing instances shown here fit that criteria.

@Odo Interesting. Lemmy is somewhat strict in its definition of "active user". You must post to be "active", so all lurkers aren't counted.

I'm not even sure commenting counts toward being "active", though I'd guess it does.

So user growth without growth in "active users", especially on smaller servers, is plausible.

So it excludes commenters? Guess I'm not an active user then
