Yes, we are back to serving ads through out the site, including pop-unders (not pop-ups). On the forums themselves we only have the sponsor's advertising at the moment, but we might have some changes there as well in the future. Please note that paying members on the forums have the option to turn off advertising completely on the forums themselves.
As to the content of the ads. We pride ourselves on TCS being a family site, and I have no wish to have objectional advertising running on the site. I only setup the ad code yesterday and did put in filters that are supposed to filter out tobacco, alchohol and anything of a semi-adult nature (none of the networks we work with server sexually explicit campaigns, but we prefer to keep even the scantilly clad ladies out of the site
). I know from past experience that these filters don't always work 100%. I keep checking on the ads myself, but it's more than possible that I won't be seeing ads that you are seeing (ads are often geo-targeted).
Please, if you see any objectional ads, do note down the name of the advertiser (just hover your mouse on the ad and write down what shows up in your status bar). This will help me get rid of the offending campaign more quickly.
Thank you for your understanding and cooperation.
