I remember back in my good RO days, private servers running off from real donations (not cash shop disguised as donations) and ads, struggling for survive. Best servers ever.
But from some years ago, people are just opening servers just for the profit. They don't even care about offering something unique, almost every server is equal: woe servers, non renewal servers and even those focused on a real "classic" 2-2 experience are just copy pasted, just seeking money, managing it like they were Gravity itself, treating you like a customer instead of a user who is enjoining the time in the server - which is a problem too, as this kind of servers produce the most toxic and condescending community; those who think they have the right to criticize everything and demanding anything they want because otherwise, they'll go to one of the other copies. Eventually admins accept those term and in the mid-run, the server gets boring, people no longer "donate", and the admin closes the server to open another one and earn more.
As a Spanish player (from Spain), I've seen this in both, the spanish and the international community. I remember back then famous spanish servers like SaltitosRO, AnaedasRO, etc. And even a bit more recently but still old, international servers like Eternity RO (they had pay-for-donations, but at least I felt there was passion in the project, I might be wrong).
But now, it's just kiddos running an internet business. Trying to gather users like they were selling shampoo. It's a bit sad.
Sorry for my English.
