Had a feeling you were going to say Calshot when I started reading your posts.
At Calshot I have often found that the abrasive sandy paint used on the walls comes of the ply easily. As this wears off behind the holds from them slightly moving they get a bit of a gap behind them and spin. You can normally hear the crunch of the sand as they spin.
Were the spinners in the main on the wall to the left of the competition (overhanging) wall? Found a few there myself the other night. That wall has just been re- furbished and I was finding the issue worse there than usual.
As for the tightening your own holds, I guess I have always been used to the policy as it has always existed there. Calshot is a bit of an odd one as far as climbing walls go as the wall isn't the primary financial driver of the centre. As such it can sometimes feel a little unloved by the county council in terms of staffing and regularity of setting. (Although the excellent staff, in particular Anna do a fantastic job of setting routes in the time available to them). As such self tightening the holds sort of feels like helping pitch in at the wall. There is a lanyard to attach the allen key to your harness so you can't drop it on your belayer. If you don't feel confident then perhaps ask the staff then?
I'm in no way connected to the facility other than a very regular customer!
