I know some ip-addresses here that try to send me viruses for over a year! Posting this to the abuse I did once or twice and indeed doesn't help always but I also block the ip at the MTA level (postfix) and that does help ;-) Some I have even blocked at the firewall because they wasted too much of precious cpu-time. Countries like TW, CN, KR I have blocked at the MTA level, although only in big (/16) ip-ranges and domain-names, this tiny TW ip-range you mentioned here I have not blocked.
twtelecom.net is in the US.
By the way, I wouldn't report spam to the abuse-addresses, the reports are often forwarded to the spammer. It is often only used as a confirmation that the spammer has found a working mail-address and you will get more spam. Spamcop offers an option to report the spam without sending mails to the abuse addressess.
I'm not certain many spammers do really care to clean up the address lists...
