It seems as though most providers have found a way to circumvent the blocks, apart from the first few weeks of the season i can't remember using a VPN. reading most forums and this reddit sub it seems like this is no longer a huge barrier for IPTV and that lessons have been learnt. Blocks are a blessing in disguise for me cos it shows who to stay away from and its no surprise that its mostly the newcomers who are struggling.
I'm fairly sure the ISP's can put in place much more sophisticated blocks but you need to remember that BT Virgin EE etc are forced to do this by the courts and will probably do the bare minimum to comply.
my provider is [beams-tv]( https://beams-tv.com ) i know a few will be asking
BT, Virgin and Sky doing the bare minimum? They all lose money from IPTV so I bet they're doing everything they can
