SOE doesn't delete posts they don't agree with, they only delete posts that go against their
posted rules.
I have been able to express my opinion all I want in the civil manner even talking directly with devs. Just like on this forum if things turn to flames or go against the rules the discussion ends.
The spam is bad on all busy servers and I'm sure SOE is working on something to help combat it. I bet they hate it even more then you do because they have to deal with tons of angry customers, dedicate $$$/staff to combat it, etc.
