I found this blog post from Eddie Davidson rather shocking: https://storiesonline.net/blogentry/58936
This is also not the first blog I've seen about this. I know that BadSammie wrote a blog post about the topic as well and so did some other authors in the past year.
I've been a part of this community for two decades now and I want to see it continue to be healthy. If there are rotten apples, then we must see about finding ways to remove them.
One of the things I can think of is that Lazeez puts up a warning that trolling authors won't be tolerated. Freedom of speech is one thing, being an asshole is another.
On top of that, maybe we can also get button to report these kinds of people to Lazeez?
If he receive multiple of such reports from different authors he could give even give an autoban, or alternatively ban people after reviewing the messages. It would also be nice if that person is auto blocked from sending messages to you again.
I know that this will cause more workload on his end, but he could even hire a volunteer moderator to handle it for him. Without some form of community control it'll be hard to get a handle on this situation.
