Runelocus is by far the biggest site where people look up servers, at least more known than others if I were to guess?
Thing with Runelocus is also that the spots at the top of the list might not even be for sale and are reserved for sponsored servers. Some spots you also have to pay months in advance or might not even be for sale at all because they're taken by other servers.
And that's where the rewards will take a spot,
if you really think that people ing ( who actually play the game not like a hour a week ) will vote just for the sake of the server, then you're mistaken
unless you make their gameplay a bit more fun with high value rewards or more like something they actually want, they won't vote at all
When I say forcing them to vote for high rewards that changes every month, I actually mean they abuse the hell out of the voting and vpn system over the internet, otherwise 50 players won't be able to get the game to the 3rd page
Updating the server is something should be taken into account as well,
its more like a circle that we will never get out of it,
Less players --> not worth thomer time to update it weekly --> less updates --> people leaving because lack of updates --> repeat.
