'Someone is trying to use your client to spam 'some IP', please urge hub owner to fix this'

Getting this over and over again. Tried various firewall settings, 0. Did a little google, appears to be bug in hub soft.Contacted OP, after hour efforts he's blaming client(ApexDC++ 1.2.0Fin)

That is not a bug in ApexDC++. That message means that the hub you are logged in to is used for CTM flood, aka DDoS attack. If the operator in that hub strongly denies that it's hub issue, I'm 99% sure he is responsible for the attack. Please leave the address of that hub and I can check it out if you like.
