I use MT 3.2 with SpamLookup enabled, and recently moved to TCH after an incident of spam at my old host. This company was included in a list of MT-friendly hosts, and this seemed important as my old host's actions seemed to demonstrate that they had neither any interest in blogging nor any sensitivity to blogging hazards.
Basically I had a huge run on my trackback script, which caused their server to grind to a halt, and they moved my entire site off the server rather than just the TB script. I wrote back explaining what had happened (within a few minutes of getting an email informing me of the action), but I got no reply and so started looking for a new host.
Anyway, what I was wondering is (a) if TCH would remove an entire site or just the offending script and ( if TCH makes any allowance for such hazards when monitoring bandwidth? I've taken due precautions (like renaming my TB script and removing references to trackback from my templates), but would TCH allow spam attacks and malicious denial of service attacks to force a customer off the web? And do renamed TB scripts ever get spammed?
