Dunno about giving the power to delete with enough rep.
Making it where you have to have x amount of rep to make one should be sufficient.
Remember we all have the ability to edit existing tuts, so if you feel a tut is lacking you can always add to it, just so long as you don't detract from it.
However, the tuts talked about here.... seem as if someone was trying to be an ass.
I'm sure Ashley/Tom will make suitable adjustments.
