Lots of factors to consider. No one likes to see pay to win but few answers are given. Owners are left to build around a void without definitions. It seems the only real way to fix this problem is to have a trusted domain running a membership type voting site where boosting is mathematically impossible. (This is the main reason for all the problems, list sites and the way they function opens an endless instability into the niche where a select few float above on exploits or ironically enough are forced to pay to win players in the top spaces.) And yes a lot of it is greed. There are actual costs for hosting a server. In my case a dedicated server, VPS, domains, and taxes. While I might make enough to keep the server afloat and invest back into the projects. It is no where near what I've heard some servers are making monthly... Enough to buy a car? A house? I mean I'm no one to judge but if you make that much from a game server shouldn't you be investing in the community that gave you the funds?
Just my 3 cents.
