Weird set of 404s???

Hi there,

recently, checking my 404 logs, I came across a bunch of weird
requests, never saw before. Seems like some kind of bot, but I can't
think of a good reason for such URL guessing. Does anyone?

Some examples:

1 /accomod.htm
1 /acivit.htm
1 /attract.htm
2 /cgi-sys/formmail.cgi
4 /cgi-sys/formmail.pl
1 /comcri.htm
2 /comedu.htm
1 /comeet.htm
1 /comeme.htm
1 /comguid.htm
1 /commed.htm
1 /compub.htm
1 /comrel.htm
1 /comsoc.htm
1 /dining.htm
2 /joke
1 /myswl
1 /services.htm
1 /shopping.htm
1 /sportrent.htm
1 /transport.htm

Thanks,
Murilo
