I just emailed Agoda and asked to be removed and I have been. Here's their reply to me.

I don't know if this is any help - but I logged into Agoda YCS and put each of my rooms as unavailable for 12 months, so I don't show up if anyone searches Agoda at all. This may not suit some people, but Agoda kept discounting my rooms without my consent - sometimes 23% or more, so I am happy not to show up on their site.
