Before I changed my ISP, my former ISP had drastically slowed my internet speed after I installed Tor. Is that even legal,as far as you know?
Of course, I'm not talking about internet speed when connected to Tor, but when not connected to it.
I think this is not what happened, your ISP probably did some Deep Packet Inspection and decided that it would decrease your connection's speed. This happened to me every time while trying to download Torrent. Basically my connection was going 100% of it potential if I was browsing the web or watching YouTube (regular stuff), but would drop to 0.1% if I dared download Torrents. Also, your ISP cannot know what programs you have installed on your computer, it can only see your internet traffic. Sadly, this is legal and even encouraged, as it allows regular home users to do their stuff while downloads are slowed down, because internet lines in Italy are worse than those in Africa (not a joke).
È una soluzione all'italiana: Invece di potenziare le penose e vecchie infrastrutture, penalizzo chi scarica file.
