tom's guide problem

hey guy had a bit of an issue for a few weeks now.
every time i try to post a comment on a tom's guide article i get 403 forbidden.
i can go into the tom's guide forum and post there with no issue on the same article but if i just go by the splash page i get the error...

currently i use ghostery, adblock and opera. i wasnt using a vpn or any ip masking software/proxies.
 

yep that might be it... although i never clicked login and my tags are up in the top corner. but this time when i went to post it thought about it then let me.
i guess my cookies were outta date...
