PerpNet Is pretty much a replica and hard copy of PerpHeads, they have the same models/car mechanics/HUD and more of it ahead. The owner was banned 2 years ago for plagarism related causes which lead on to the creation of PerpNet. For now, it accepts anyone and its attracting some people from Perpheads onto their server.
To me, it seems like a disgusting thing to do, instead of making their own style of a server, they decide to create a direct copy and don't credit any of the coders or Devs.
Yes, they could promote PERP as a whole, but either way, these type of movements are snakey and quite frankly unfair and full on copies.
