Wow, this really has blown up, hasn't it?
From what I've seen, he's given credit to journalists several times but not all the time. There have also been many occasions where he Tweets something that's very similar to what someone else Tweeted (see Gerard Romero's Tweet on Dembele today vs. that of Romano's). After being heavily invested in transfer Tweets this summer, I have started to wonder if Romano indeed does have his own connections or piggybacks off of others'.
With that said, he's better than BS merchants like Nicolo Schira or your everyday ITK Tweeter/Redditor, but of course, that shouldn't be enough.
EDIT: Annie (the SportWitness journalist) is starting to get more and more abuse, but the one valid point that several have raised is why she hasn't engaged privately with Romano. Still, if other journalists are feeling the same way or have had the same experiences, then it wouldn't surprise me if more of them come out.
EDIT 2: She deleted the Tweet after the abuse that she's received.
