“We'll kill spam in two years”❗Breaking News: Spam is still here❗ This Bill Gates gem is now almost 20 years old 🎂 👇theregister.com/2004/01/26/w… And how ironic, Spamhaus researchers now observe Microsoft to be the worst ISP, placing it top of Spamhaus’ CSS List. #SpamDefinitelyNotDead #TakeActionMicrosoft

It's not difficult for our ticketing team to spot when our researchers discover a new group of spammers to shut down 🎯 Look at the spike in tickets (bottom) vs. listings (top)! One new rule and a few thousand listings in less than one week equals A LOT of angry spammers 😡 ! 🤘#ResearchersRule #TicketDeskTales

The @xs4all team cracked the @ATComputing code at @mch2022 and got themselves a nice price. Crack the code and open a locker at the ATtent

After 27 years, today marks the last day of what has been quite the adventure. As a 22 year old, while in university, we founded XS4ALL, the first end-user ISP in The Netherlands. Thanks to everyone that joined us on this adventure. So long and thanks for all the fish.
