"They were busy spamming the popular unmoderated newsgroups."
And email, via unsecured mailservers.
Spammers were costing ISPs thousands per month in bandwidth charges thanks to the relaying antics but the real attention-getter was when AT&T had to spend around $60million for an emergency rollout of mailservers to cope with the incoming volumes. I was surprised at that point that it wasn't treated as criminal denial of service attacks and prosecuted accordingly.
