Yeah, I know that if you delete
ethernet either users or discusiones the count will not be precise anymore.
Right now, that number is the id of the last user & discussion created on the forum that is publicly accessible (no deleted discussions).
In the future I may set up a new (and single) route to count entries in the database, but for now, you can get an idea
Also, it doesn't show the post number because /API/posts currently returns 500
