Fair enough, and in other cases I could see this as being an issue (particularly with smaller businesses perhaps where employees may identify more strongly with their company and its success), but in this case I just don't see it happening. As I said it doesn't really make sense at a company level, and on a personal level who would be the one motivated to punish these customers in such a way? It seems the onus would be on some individual(s) in the ticketing system to "Hey, that's one of those jerks from that lawsuit! I'll teach them to cause trouble with my company." That just doesn't seem likely to me.
