tbh the easiest way to get server names is just thinking of words and adding suffixes/prefixes.
here's some good examples;
- Cropied (Crop with the suffix -ied)
- Pvpinium (PvP with suffix -inium (titanium))
or if you have an idea for the gamemode (Prison, Gens, Box, etc) just pick a word and slap the appropriate ending on to it. :))
