The time control is your allotted time to "Play".... not stall or refuse to resign in a lost position... as long as you're playing there is no issue regardless of how much time you take. No one (at least not me) is complaining about some one using all there time. (Or trying to flag me, or anything else as long as they are playing) The issue is when they are no longer playing, and just won't move. That is stalling, it is against the rules, and I always report it. I see it fairly often in 5-5 blitz so it's not that painful to wait for the clock but anytime it happens I block and report.
So, though you take issue, there is a rule on stalling, it is defined, and if you are purposefully letting the clock run simply to stall or lose on time, it is against the rules and repeated abuse of this rule will get you account closed by chess.com
Ok, this is my last post.
There are several things being discussed here.... but to the matter of whether or not Stalling, as defined by Chess.com (and by me in my early posts) is against the rules. IT CLEARLY IS!
Whether you report it or not is up to the individual, and maybe some don't think it's poor sportsmanship, rude, being a jerk or whatever.... but it is against the rules regardless.
Read the link that was posted if you have any doubt.
Still, issue is taken here. There is a time control for a reason.
