According to Vod's BPIP database, there are 326,673
Active Profiles.
That will say that those account have been active for the last 30 days.
Of course many people log in not so frequently, so those numbers are approximate
And only 30k sent or recieved merits?
Granted a lot of the rest will be alts/bounty or spammers but not receiving a single merit is a bit weird. Thats less than 10%.
Granted some will be bots parsing the forum or copy-pasting but still, that number is ridiculously low.
