He called out the hypocrisy of many journalist’s output for many years. In many posts showing them having the complete opposite viewpoints over the years over the same issue/different teams.
They didn’t like it and formed a ‘WhatsApp’ group that went after him, Doxxing him (releasing personal info).
He has previously exited Twitter , due to the strain and mental toll caused by ‘journalists’ appalled that someone spent the time exposing hypocrisy.
This time he’s left Twitter for nonfootball reasons AFAIK, but the strain and mental toll will be similar.
Hopefully he will be back in a year, refreshed and strong again, but that’s just a selfish hope, it’s up to him how he needs to live his life to survive, and the cesspit of Twitter is probably not the best to assist in that.
