Thanks to our own HoldenHamlet for this find: It appears that CD hacks and skill spammer hacks have been shut down in an unreported piece of recent updates. Reddit user Ninjamonke wrote that it appears that the death of these hacks is legit from statements made in the BDO bot maker's Discord channel from both staff and developers of the programs.
I don't know if you guys found out about this but all those skillspammer/no CD hacks have been patched from the recent update. They're now server-sided so you won't see hackers running around with those hacks nor will there be any 'silent hackers' who hide their skill spam. Speedhack seems to be detected only but it will get you banned.
Also, another banwave was done last week after the announced one.
So the only thing to worry now would be bots.
