My wife's blog/book site gets less than 25 hits a day typically. We have a downloads page where we offer her first book for free in multiple formats.
Over the past 2 weeks or so weeks or so we've had upwards of 50 downloads of the book per day - as reported by our download monitor/wordpress plugin. There's a few different downloads on the page, but only the PDF one is getting the insane amount of attention.
The IPs jump around all over the globe - russia, india, pennsylvania, montana, uk, canada, etc. But none of them repeat and there's typically a few minutes between downloads (and sometimes we go 30-40 minutes between).
Still, something about it all just seems a bit off. Also, our traffic hasn't increased at all so they appear to be hitting the download link directly.
Again, we're giving the book away for free so we're not worried about that, just want to make sure something fishy isn't going on here.
Anyone have any thoughts of what this could be or how to look into it a bit more?
I'm using the download monitor plugin but no one else seems to be having any issues with it that I can see.
