@Mald My thread isn't just about you, or I would have mentioned you in the OP. However, by the comments I would say you may have to re-review certain aspects of the way you moderate.
It's good that you now comment your reasoning for locking threads.
Two smaller points:
Temp-banning someone because they're complaining about you is pretty OTT, if you can prove his claims are slander and you don't mind proving it then of course a temp ban is reasonable.
I feel a bit bad because you get no reward that I can see for moderating however, I do believe you can and should improve your moderating skills.
