create separate server block for each domain name

server {
  listen 80;
  server_name abcd.com;
  ...
}

which will be used when nginx detects the domain as abcd.com

without this block, the redirection will go like this:
NNN.abcd.com => abcd.com => . (dot)

with this it'll access correct site instead (stop at abcd.com)

catch whatever that matches such pattern (asd.com, fghqwe.net,
zxclkj.org, asdf.ghjk, etc) and return 403 (in this example)

without this block, the previous server_name
(~(.*)\.([^\.]*)\.([^\.]*)$;) will catch this pattern and redirect to
'.'
