Betpanda stole money from him. Of course he is anti-Betpanda.
It's obvious that he is not happy with them.
Is that an alt account of yours? If not, then how do you know the ins and outs of the person? Those who are anti of any gambling site may post fake accusations especially while the user has no reputation and/or nothing to lose. While a user creates a scam accusation against any site, the user should provide enough evidence, and the accusation should be opened with clean hands.
