Yes, when I'm able to I check who is logged in or checking me out when I'm on break on SM. That's not overbearing; that's just good business practice.
It can be frustrating at times, but it's not uncommon for guys to write me long-ass messages on the free chat screen when I'm on break, because they assume I'll see them and respond. Which isn't always possible, and isn't the smartest way of getting my attention, but when I'm able to follow and respond, I do. They do it when I'm in shows with other guys as well, and in those cases I find that rude and never read or respond. But there's an expectancy there, that we will monitor our chat when we are not there.
