@GordonFreeman - It's highly specific in nature. You may open a sqlite database and store played time.
make an amx file, connect it to the database... check for connected players... load / save played time... then whatever function u need for checking inactivity of player...
... it's after that u can search for that entry in csstats.dat and reset it as per the natives.
If you don't like my idea, then you can yourself edit the source attached and recompile as per your wish and if you like, you may share with us too... It's open source... you can do anything as you like.
