We ALL "abused" that glitch when it existed (I mean all bee farmers did). It may be gone, but bee farming is still a very good way to make money, assuming you know what you're doing, where to do it, and how it's done.

By the way, I also hold all my bugs till their respective bug day (where you get 1.5x the price). That's definitely the way to do it. It goes for bees as well. Goes for bees too (especially bees, mind you).
