I agree, but people said that the spammers wouldn't be able to deal with BGP route advertisement but there was cases of spammers injecting routes sending out spam then removing those routes. Wlan is easy.
Spammers come from every walk of life including the various technical professions. Otherwise where would all the spamming software and web-scraping software come from!? Just because someone is a technical expert in BGP routing doesn't mean that they will use their skills the way that many NANOG attendees would like them to. Even in the early days of spam, the green-card spammers hired a technical person to set up servers and write spamming scripts. And let's now forget the uber-hackers who create the scripts used so effectively by script-kiddies. And let's not forget, these spammer geeks learn the knowledge from the same places as everyone else, including the NANOG mailing list. I reckon there is a 99.95% probability that there is at least one NANOG subscriber who is a currently an active spammer geek. So if WLANs were relatively safe yesterday, they won't be safe from now on. Of course, if spammers are reduced to driving around major cities in vans generating 802.11b radio traffic, it might be a lot easier to catch them... --Michael Dillon
