I think that's why people donate, to get something back. I know donating really is giving for free, not receiving something back, but it is already become a word everybody uses.
And Realsoft server has already become more than just a "download-and-run" server. Realsoft uses more time for scripting and fixing the server than many other GM's out there. And if Realsoft keeps doing the stuff he does, like I belive he will, his servers will gain much more players. And getting 100+ players online isn't a easy job for a old school server. Classictibia has that, but then again it is advertised on otchanger.com, where many tibia players come to download the ip changer, which for sure boosts up the players online.
