Is this an [censored] thing to do?

[Go Blue]

At first I thought the following was just something that happens occasionally but now, that it happens to me several times a day, I think that people are doing this on purpose. Anyway, I don't like to post out of position, unless I come in right behind the button. I wait for the BB, and the person to my right posts his BB when it gets to him, but then sits out the next hand (where he'd be the SB), thus not allowing me to post my BB and making me either post in LP or wait another orbit. Does anyone else have this happen to them or is it just me?
