Unfortunately, there is no "fake" xyz server in RMS because servers are allowed to have the same names. There are in fact servers running with the same names.
If it was
just a server with the same name I wouldn't care at all, but they are
specifically pretending to be the old server by saying things like
"OathRO has reopened and this time for a decade" whilst impersonating staff from the original server and taking logos exclusive from the original server that they do not own. That is what they are advertising themselves as and it's just flat-out untrue.
That's not something you do if you just want the same name. You do not need to lie and claim you are the original server and are restarting whilst pretending and impersonating other people. That is extremely suspicious to deceive people like that by pretending to be something you're not, no? Nobody with sincere intentions of starting a server with the same name does that.
