Subject Lockouts

Who and why do ppl have a say on these forums then lock them out before they get commented on...Is it a case of hit and run?

Normally I lock threads because they have drifted off from the topic of the thread. In some cases, I split them off into their own thread if the topic is postworthy. Also posts get locked occasionally if they are in the wrong forum (as this thread was posted in TAC/U18. Not in General VFL chat (the main board) or somewhere more appropriate.
