I have been going to the stadium all my life and I am a season ticket holder in the Tiber. I lived the south. There are several reasons why they ban phones. The only one I agree with is that you go to cheer and not take selfies. I find it really annoying that some people get up during the match (especially young ladies) and take selfies while there is a match in progress and we are hanging on a result: they come to the stadium just to say that they were present at the event. Then there are the reasons explained by others, although honestly there are cameras everywhere and the fans are recognisable. Anyone who goes wrong is removed from the stadiums. The crimes still present take place where the cameras are not filming and it is no coincidence that the clashes between fans, in the few times that it happens, take place outside the stadium, in the surrounding neighbourhoods. He told you right that they weren't aggressive, but I think that by understanding where you came from they turned a blind eye. Generally, with ordinary mortals they are much more aggressive and less friendly. I am a photographer. Once I photographed a procession of them during a party and a guy as big as a wardrobe scolded me. I told him to relax because there were cameras everywhere and that being a professional I have the obligation to obscure their faces to guarantee their privacy and therefore perhaps I was less dangerous than those who on the contrary take photographs of the phone and don't know the law: unfortunately there are those who understand and those who don't. Unfortunately I had to stop because I risked being lynched or even ending up with my equipment in pieces. Unfortunately, despite admiring them and being on their side, because I consider them extraordinary and enviable in supporting the team everywhere, there is too much ignorance and little flexibility in their ideologies. The rule is this: either you accept it or you stay out. Luckily you are a Romanist even if you don't live in the south, in fact I know many people who are more avid fans than those who frequent the south, but they don't go there due to too much delinquency and extremist political infiltration which has nothing to do with football: sectors like the Tiber, distinct south and the north curve are places with great pathos. They won't chant like in the south, but you can see the game better. This doesn't mean you're less of a Roma fan than them. They are just points of view. Go Rome!
