Yes, pureaim.org is a completely fresh start, which means there are new Counter-Strike: Source server IPs, and existing ranks, stats, or accounts cannot be transferred over.
Over the last 15 years, a massive amount of legacy data accumulated within the old system. To ensure maximum stability and better performance, the decision was made to implement entirely new structures and start with a clean slate.
You can find the new server IPs directly on the website
at pureaim.org or join the new Discord/TeamSpeak to reconnect with the community.
