I am not a buki in halacha but I’m sure someone who is can come up with a situation that it “legal genaiva”.
Unfortunately, there are many people who think that there is “muttar genaiva” or “illegal yet muttar”. We don’t promote that on Yeshiva World although some people might think it is Yeshivish to pull shtick, we believe that if it is illegal than it is probably assur (and if not than it probably shouldn’t be publicized online anyway)
