What's with these $%^* Moly Bolts
Following the instructions, I install it into the wall and then tighten the screw to expand the moly, but the moly turns with the screw and rips out the drywall. The result is I now have a hole in my wall as big as the moly. Totally useless.
What's the trick to these things?

I have no experience with these type of anchors. This is what I found here: Molly Bolts | How to Choose the Right Hanging Hardware | This Old House
Since you now have a larger home I would recommend toggle bolts or "Togglers". For new wall locations I like to use zinc or plastic "zip" anchors
How to use them: Seat the round flange flush with the wall surface by tapping the screwhead. Turn the screw to "mushroom" the slotted sleeve against the back wall surface. Take care not to overtighten; you'll know this is happening if the anchor flange starts to depress the surface of the plaster or drywall. Once the molly is secure, unscrew the bolt and then replace it with the item in place

Be sure the thickness of the wall matches the recommended thickness on the package.
In the end though some molly bolts just don't collapse when you tighten them. Poor manufacturing is the problem. Buying a different brand the solution. The maddening part is you are left with an ugly hole. I've even see packages where some will work and some won't. Maybe just avoiding mollies is the only way.

I asked someone more knowledgeable than me and he told me they're designed for hollow doors and not drywall.
