Translation of "Dodgy" in Japanese

This year again I found a number of dodgy goods so I'll introduce them all here.

今年もいくつか怪しいグッズを見つけたので、それらをまとめて紹介しよう。

Then what is this I wonder? If it isn't dodgy door-to-door sales then could it be a new kind of pickup technique for the ladies?

これはなんだ。キャッチセールスじゃないのなら、新手の逆ナンだろうか。
