No. Its not down, they are still up and running, just under the name 'PowerBot', because apparently Jagex whined and moaned to the Cyber Police, and they got involved, and basically, Jagex got the domain 'Rsbot.org', so now RsBot is powerbot.
Its not really funny, As a former P-Mod Jagex were really stressed out ab they couldent block it, The funny bit is its actually really simple to block but jagex dont know how to :laugh:
JaGeX could have stopped them much earlier than when they did, they just had to practise their Trademark and copyright laws and bring that up in court, clearly they didn't put that much effort earlier.
