In 2024 I have personally received 757 guaranteed non-spam emails from
addresses that match your above regex. After removing .us, the number is
525 so far this year.o

Out of those 525 wanted emails, here are the TLDs in use:

    394 tech
     71 xyz
     32 email
      9 rocks
      7 asia
      4 space
      2 fun
      1 works
      1 top
      1 technology
      1 pro
      1 live
      1 computer

In conclusion I personally would not use anything like this, I would at
most slightly penalise via spam scoring those above that had 2 or fewer
hits. Even then I might want to correlate this with which TLDs actually
appear in known spam so as to not just penalise any new TLD.

For all time (not just 2024), the breakdown is 2,379 mails and:

    613 xyz
    596 tech
    456 pro
    336 email
     52 technology
     50 space
     46 rocks
     39 asia
     28 top
     26 online
     26 link
     24 work
     19 club
     15 ninja
      7 world
      6 fun
      5 site
      4 click
      3 wang
      3 solutions
      3 science
      3 london
      3 host
      3 computer
      2 net
      2 live
      2 guru
      2 gdn
      1 works
      1 win
      1 website
      1 vip
      1 help
      1 global
      1 berlin

Thanks,
Andy
