I'm okay with 2 through 4. 1 is extremely irritating to me. 5 is hit and miss, but honestly I tend to avoid people that do this. Primarily because it can lead to a great deal of confusion, so I think it's a poor practice in general. If they're doing 6, I would probably just avoid them altogether in most circumstances. They can have fun with people who like doing things their way if that's what they're into, but it's not for me. Then again, it can depend on how far I'm willing to suspend my disbelief for what they're trying to do. Unfortunately, people often tend to take things too far.
