A few things:
1. TERB is not a democracy, no hosted board is. The admin and the mods are the final say.
2. If you think a handle is a new incarnation of a previous banned member, flag the post(s). The mods and admin can check IP addresses for matches and routinely ban new handles, especially for well known trolls.
3. If you want to know why something was deleted, you are far better off asking in a PM, or using the report post feature. Most mods don`t respond well to whining and moaning in public.
4. The mods at TERB are among the better ones out there. On the Calgary based board for example, the mods break the rules themselves (insulting members in particular), are known to be biased to certain paid advertisers they have friendships/relationships with and love to delete negative reviews and ban those who insist on posting about bad experiences with their favorites. Then there's the 411 board, where mods out posters, and they have made some of the worst trolls mods themselves.
All told, we got it pretty good here.
