Awesome thing about having a gmail email these days, Is all you have to do is click select all > un-subscribe and filter these msgs as spam and youre entire inbox is clear in 5seconds and instantly unsubscribes you from all the lists. I remember people used to try sign up my email to spam lists but within 5seconds I had blocked them all. Someone tried it recently and it fails badly for them. It would take them hours to sign me up, but only 5seconds to permanently block all emails from there adresses. Sorry spammers! :)
In the olden days we had hotmail which wasn't as good as doing this, luckily were in 2018 and technology can beat any bitter butthurt people on the internet.
