Here's what I do know, it's not my IP that's banned because I had it changed 3 times already (and last two parts were changed twice, third time it was first + last two parts), I've also tried changing MAC twice - no help.
I sent emails to kijiji over and over but no reply.
If I connect to the network from a laptop (borrowed one) I can post just fine so they somehow banned my COMPUTER (nothing to do with IP/MAC).
What else can I clear/delete on the comp so I fix this?
