The spam came back somewhat yesterday, and although I knew it would eventually I was still disappointed when I saw my inbox yesteday.

Most people probably don't realise it, and I didn't have my site up at the time, but several weeks back an ISP in the Northwest, McColo, was taken down by it's upstream providers. This ISP was also the controller for a massive botnet that generated quite a large amount of the spam on the internet. For my business I have one email account that has about two dozen different email addresses pointed at so suffice to say, even with a spam filter that blocks 95% of the spam that those accounts get, I still receive about 75 spam messages per day. Since McColo was taken down I've received an average of 10 per day.

That was until yesterday, I open my email and wake up to find 30 spam messages in my Inbox, not anywhere near what I used to receive but it does herald the return of the botnet that was operating out of that ISP.

So it looks like the spam is starting to come back.
