What's the problem sight, i actually said that we were ddosed again today
And you call that offtopic, you seriouslly need to look up what is offtopic and what is ontopic.
Since vac-secured has a close relations with the ddosing problems as baz said updating/patching the servers.
Stop the freaking prejudice !!!
VAC = VALVE ANTI CHEAT
do you see "VAD = VALVE ANTI DDOS" ?
so yes that is offtopic, VAC secure doesnt mean updated or outdated, VAC works on some versions of HLDS and on some it doesnt anymore, its just pressing your luck.
also if you are VAC banned you cannot join any server with VAC security, VAC has nothing to do with anything of the attacks

now i gave you a warning for 5% because you are so smart, and you could google this all easy, a simple google solves all, you are the one prejudging here by accusing me a lier for calling that an offtopic.
ps: for the lazy people
