Illegal stuff has been happening on Telegram since forever.
Don't get me wrong. I am not saying that I've discovered the true machinations behind the arrest. Just bouncing my ideas.
most of it? i dont think there much reason to arrest him since they have been complying with western Governments by blocking Hamas related channels on Play Store Telegram version (though you could have 'uncensored' Telegram by using apks).
I think Telegram does need a purge, its ridiculous how blatantly and openly child abuse is being sold there. not to mention the fascists, keep in mind there are many insane Zionist channels as well.
I saw it as more being related to Russia's heavy usage of it as the method of reporting.
the official Hamas twitter account didn't last a few hours and facebook keeps banning accounts of Bilal Ahmed Al-Ahmed (Hamas sponsred musician)
