Spam/Spy?

[MarkN]

I just started to use StatCounter. It reports that 37% of the hits on my web site are from Comcast itself, not from a viewer using Comcast as his ISP. Those hits are from an unspecified country and are reported as "Visit spread over more than one day".

I was wondering whether StatCounter will report hits from a spammer, whether or not those hits result in something being posted on my web site. I have spam blocking code on my site to prevent posts. And my own IP address is set not to be reported by StatCounter.

The other possibility I was wondering about is that Comcast (my ISP) is monitoring my web site. Or, that someone masquerading as Comcast is monitoring my site.

Has anyone experienced this sort of activity before? Thanks.
