I guess more generally what I'm asking for is to be able to tailor the drain for myself.
This position reinforces my initial concern, and should be anathema to community building interests.
It's the first step in Balkanization of this community. If everyone did that, you could have groups of people in echo chambers ignoring others.
The greatest danger in this community is not disagreement, but insularity, cliquishness, and parochialism. Allowing people to silence voices they find annoying is antithetical to dialogue, which is an integral component of a community such as this.
The promise of a project like TheManaDrain is to build a community of interest; to bring people together around a shared passion. The selective silencing of others and individuation of content you seek is utterly inconsistent with that goal. Even more so if accomplished stealthily.
