Poker Concerning preflop stalling players

I've wondered something about people who take their time on basically every hand preflop for a long time now: Just what the heck do they even think they're accomplishing? What advantage do they believe they're getting? I mean, if we're near a bubble but not hand for hand or something then yeah, pulling something like that every few hands, sure. But I see people do that THROUGHOUT a tournament. What is going through their heads that would lead them to believe this is a thing to do? Especially when we ARE hand for hand and it not only accomplishes nothing but puts them in more danger since the blinds raise with fewer hands played.

Some do it because they are multi-tabling. When they see a bad hand they let the clock wind down, buying them more time to concentrate on another table they are at.

Some do it to make others think they have something (they don't), it's a ploy, bet and knock their (_!_) out.

Some actually do it to slow the game (they have chips, the blinds go up, it favors them).

Some actually do it to irritate others. Most players online are very anxious to play, having to wait is torture to them.
