I do volunteer work at a youth organization in the Netherlands. Recently smoking has become a lot more popular. Nearly all kids between 18 and 25 smoke here. There is also a very clear group effect. People start smoking because others are doing it.
My site has nothing to do with football though. And Allot seems to be running the DNS server that your ISP uses so they are directly responsible for the block.
I have my own dedicated IP range. And they specifically blocked my domain name, not the addresses. I don't know what the reason is. I have been trying to find out since the start of this year.
Creator of pixeldrain here. Italy has been doing this for a very long time. They never notified me of any such material being present on my site. I have a lot of measures in place to prevent the spread of CSAM. I have sent dozens of mails to Polizia Postale and even tried calling them a few times, but they never respond. My mails go unanswered and they just hang up the phone.
