Wil Wheaton is a good actor, a good writer and seems like a decent person. I actually once met him and I like him.
He is, unfortunately, also an easy target for trolls*.
Recently he left Twitter, for good reasons, and, because he thought social media still has a future, tried Mastodon. He recently published the story of how he got run off that as well.
He still has his blog. Everyone should have a blog.
Least I Could Do has covered this as well.
