I'm in process to block a particular geolocation from accessing my site. But i am not sure if this is going to raise any flags on my website. Basically i'm getting lots of spam from particular state and there are some webmaster copying my content without any attribution or backlink. I feel that is enough and i wish to save my bandwidth on that state or geolocation.
So my question is how to block particular geolocation ? Do you have any suggestions for php scripts that help block particular geolocation ? and another question: if there are any SEO disadvantages ?
