Two thoughts on this.
1) Enworld is "Grandma Friendly". Would you put your grandma though this?
2) This isn't the first time this has happened on the net, nor will it be the last, but it is truly unacceptable behavior. Whatever made him do this, simply accepting it and welcoming him back is not the right answer.
I've always thought of Rev as a nice guy, and because of that, I never thought twice about this being a hoax when there were clear signs that it was. Numerous people here, and even not here, spent countless hours worrying, praying, and trying to see what they could do. You could have easily had people send money thinking that might help. Heck, my grandmother has been praying about this because I mentioned it to her. Not to mention all the people who have had to deal with a flood of memories of when their loved ones were in the hospital or in a coma.
There is nothing acceptable about this behavior. I wish him the best of luck, and hope he learns from this, but letting him back in is simply patting him on the back and saying "It's ok, just don't do it again."
