• Typing Kristin is also changed but I don't recall the result
Sigh...I am fairly forgettable.
I agree that an owner has a right to run their site as they choose, I would just think they would be up front about what they are doing. If you are changing or substituting names, just tell people, especially if it is in their PMs. Why wouldn't you just to avoid the grief? If they aren't up front, then I might have to pause and say, why aren't they being upfront and what else are they doing that I don't know about? selling my info? putting cookies on my computer? Other computer stuff that I don't even know enough about to know what it would be?
If someone tells me up front, great I use at my own risk. But if someone buys a site that has been very trustworthy for years and starts trading on that trust without telling people that the rules have changed, then I become a bit concerned. But each person has their own level of tolerance for different types of conduct.
