There may be ways to know for sure that you aren't the only one, but there is quite a lot of one-sided information in the world and the internet tends to be bad about this. Many people seem unaware of the possibility that maybe something was lost in cyberspace, so if you don't get a reply or read receipt of some kind, it is not unreasonable to send a follow up email and inquire. I tend to send replies to make sure people know that I got their thing, but I have had to reign that in over time because it goes weird places socially. We really have not done a good job in the online world of finding a way to confirm that two-way communication has happened. In person, you generally are going to have a good idea if they heard you or not. Online, it can be pretty difficult to determine. And then two different people doing the exact same thing can get interpreted vastly differently. That doesn't make excessive emails less aggravating, but online communication is far harder to do well than many people seem to realize. This anonymous chewing out is not a good faith means to resolve anything.
