I wish this is a good place to post this issue and someone here might be able to give a solution what I'm looking for.

Normally most of us use google analytics to monitor the traffic of our site. From last few days, I've seen unusual activity at my site- I can't tell what page, all it says is that the active referral is "claim64843289.copyrightclaims.org". When I tried visiting that site, I got redirected to "http://www.alibestsale.com" which is not related to the site. This is all the information I have.

I don't know enough about what all those things mean to know what is going on, but the referral being called, "copyright claims" makes me think I need to at least be sure it's nothing. I'm doing the google search but still searching.

Can anyone provide some guidance?

Yes bro...sorri about dat...the solution is to block the Ip of the address....its just some blackhat SEO coys dat use dese fake links....it deceives u in thinking ur website has a lotta visitors.....anoda is floatingsocialbuttons.com ......so just add de link a blcklist tin ur analytics dashboard. I will post some screen grabs...or maybe a video to help u latter........right m caught up in a traffic jam....don't panic ..it happens to everyone.

Ensure you are not infringing on any copyright. Before you block the ip of the site, make sure you visit the site to get acquianted with their services. You can also write them.

Thanks a lot, @oteneaaron, your suggestion seems to work for me and I would do as suggested. But dear buddy, should I do it using my ".htaccess" file or can you suggest some alternative to filtering the IP?

Next, thanks @DOCTORDONE as well, your point is completely right. That's why I had verified my site content against plagiarism.

Additionally, some of my friends also told me that the site "claim64843289.copyrightclaims.org" is actually a referrer to another site which spammer use to promote. They (spammers) somehow manage to manipulate the analytics data of other blogs or sites. And that is one of the reasons the link like I mentioned appears in the analytics data.

I found one article through google to resolve this fake copyright spam problem which resolved my issue to some extent. Just want to share it with the members.
