Yes, people are researching your campaigns. Would be nice if someone found a way to block these but I really don't think it's possible.
Thats really strange...I didn't think that service worked like that. are you sure you didn't have any ads running at the time of those accesses?
yes i am sure!i havent any campaigns since midle of july because my hotel was full or almost full so i didnt need any advertisment.Maybe the guy doesnt know what he was doing and thought that he was going to see how i rank so well in SE?
what about some strange(adult,poker,etc) entries from my site statistics every month? how these website link to me, since there is no link? thank you
What you are seeing is called "Referer spam" -- These websites send requests to a large number of non-related website, knowing that X% of webmasters will click on their site's link in the access logs.
