The "server" they had completely ignored, as far as anyone could tell,
all input: you could type total garbage lines and get exactly the same
canned sequence of responses.

Note the past tense.  Now, when I connect there, I get a 521
"greeting", from some host that apparently believes it lives in a new
TLD .11 (apparently not content with inventing new .com and .net names,
they've now invented a whole new TLD - at least this one they didn't
actually put in the DNS):

% telnet yyaahhoooo.com 25
Trying 64.94.110.11...
Connected to yyaahhoooo.com.
Escape character is '^]'.
521 64.94.110.11 Recipient domain does not exist
Connection closed by foreign host.

Actually, the wildcard shouldn't have been inserted in the first place;
when it was, .com and .net should have been immediately handed over to
a more ethical custodian.  But Verisign doesn't seem willing to remove
the wildcard on their own (hardly surprising), and ICANN appears
unwilling to do more than scold (depressing, but not really surprising).

> Bad, verisign.  Very bad.

Well, yes, but we knew _that_ from the day the wildcard went in.
