As you probably have already thought of ......
would be to limit the number of tutorials any member can make to one a day,
and don't let newbies post tutorials at all for the first 2 weeks.
and do a similar thing thing with forum posts, ie: limit forum posts to 2 a day for newbies.
that would at least limit the mop up after turds like this do stupid stuff.
Anyway, good luck
In the meantime I am turning off notifications ....
