I agree. Harassing somebody you hate is crossing the line especially if it's over a stupid reason like your hentai games being censored.
Edit- I know people aren't very happy with his decisions, but he's kinda in a lose lose situation with MaiTetsu to begin with. Don't harass the guy just because he'll censor a VN with sexual scenes with obviously underage girls. If you really want to read those scenes, go learn Japanese and read them rather than harassing somebody for them. This is also coming from a guy who doesn't like Dovac and Sekai Project very much.
