Silas-c had a habit of only posting when she had something to say that she felt was important enough to run the risk of being wasted on everyone else's ears.
Morwen used to only post occasionally in a similar fashion, but being sick and under effective house arrest for her own health kinda left her with not a lot to do, so being a wiseass on the IGS turned into something she could do without raising the ire of her 'warden'.
And frankly, yeah. People tend to respond to things they really ought not to. Some things will really get under Morwen's skin. Shit like what he's posted is a prime example. It's disgusting, it's horrid, and it's using her as the subject/target.
Blocking's also pointless when people quote each other. You're still going to see people's posts in the end.
