Sorry to hear that they were so nasty. :(
Unfortunately, that’s not my area of expertise. I don’t follow streamers or YouTubers (Italian or international), nor do I have a close enough relationship with any of them that I’d be able to talk to them and convince them to mention this petition to their fans.
The one and only time some friends and I attempted to interact with a few local content creators (to publicize our free fan games we poured hundreds of hours to create and NEVER attempted to monetize in any way), we either got ignored, insulted, or received vague answers that went nowhere. It soured me towards Italian content creators and vowed to never interact with them again.

One thing you can do: It’s something the campaign has been really bad at. Have some fyers printed up and start handing them out. I don’t know the Italian school schedule, but if universities are still in session they might be good targets.
I did it last year, first at Gamescom and then at a local uni and I think it helped spread the word.
