Yeah, those are credible sources. This thread is based on a tweet by a guy named Joshua, who isn't verified and isn't a professional journalist.
I mean, it kinda does. 1300 followers is a pretty good indicator that this guy is not a professional and has no real leads or contacts. If he had credible sources of his own, surely he would have a larger following on social media. Can't see a guy flying under the radar if he has information not even people like Dreger and Johnson have.
Sure you can have 25k followers and never get 1 rumour right. Just look at Eklund. To me, it's not a real rumour until someone working on the field reports about it. You work for CBC? Okay, might be some truth to this statement. You have a fanpage and a shitty podcast? Get lost.
