Hey,
I've read a few places that NACH can be used to avoid the tag from Data Raven, but this doesn't seem to make sense to me. Data Raven says the runner has to take a tag or end the run, if the runner avoids a tag they're not actually taking a tag and not satisfying data raven's condition. Just as it is logically impossible to take a bullet to the chest and afterwards avoid it. It seems to me that a tag is either taken or avoided, not both.
