Did it ever happen to you, that some person kept calling you with same phone number? This happened to me on several occasions, most of them were telemarketers or some kids trying a stupid prank.

Now, there's an interesting site called WhoCalledMyPhone. It's the first time I encounter this type of site. Basically, it's a site with a lot of phone numbers, you can search through their user-submitted reports an can find information on that annoying phone number. This way you can find and share information about phone numbers used by debt collectors and other intrusive callers.

The site can come in pretty handy, if you've got a lot of intrusive phone calls. It's really worth a look! Here's the site again: WhoCalledMyPhone
