Not exactly, it might seem easy but it's more time related than total posts so even If you made a 1000 posts in a day your activity wouldn't be high at all in fact the max you can get is 14 activity points every 14 days, It would take a bit over a month as long as you login once every 14 days.. So activity is more of a time based thing and not very easy imo, so for people who can't wait a month they go through and buy the accounts.. hope that clears it up
