Okay so I am having people visit my blog on a daily basis from OTHER COUNTRIES and its starting to FREAK me out. I have visitors on a daily basis from SWITZERLAND, UNITED KINGDOM, CANADA, WALES, MEXICO, JAKARTA, RUSSIA, AND MANY MANY OTHERS!!! My question is HOW are they finding my blog? I am not listed on the google search...and WHY are they coming to MY blog??? I also have a MOBILE visitor from ALABAMA!!! I don't know anyone in these places. I really dont want to go PRIVATE....but looks like I might be...and SOON!!! Anyone else have CREEPY visitors??? And hey.....if your spying from another country please let me know how you found my blog...and why...thanks!
