Hum.. yeah. I'm sure employees never pretend to make up personalities and do fake posting--oh no---never.
Like most jobs, I'm sure they don't come in on their days off. And considering how quiet it gets here on weekends, I do truly wonder if driving all the 'real' posters away would be so horrible.
I'm pretty sure they'll be going away on their own soon, though. Anyway, good luck with that.
