You are using adsense on a GPT blog. :s Your adsense account may get banned for this. Adsense does not allow gpt sites. :s

No there is no harm of putting adsense in GPT blogs only you can't add offer site and PTc site itself where exclusively people come for money purpose or members were told to open the page for money.But blogs containing information on money making site can use adsense.
