User xiaoqiqi001 posted several ad topics on the subforum "General Discussion", with content of selling false graduation certification of UND, UPenn, SU, UO, ISU, NYIT, NYU, CSUEB and CSUPomona. He leaves his contact account on QQ/Wechat (2 of some widely used online communication services in China) as 596403686.
Should these topics be deleted and put the ad robot into black list?
(I wonder why how the ad robot could pass the register steps and why it chooses to make China-styled ads on this forum with nearly no Chinese... I have to say actually those kind of ads is easy to witness on Chinese forums)
