Sure, it’s not nearly as warm and fuzzy as the late lamented Mr. Rogers - but Rotten Neighbor performs an equally valuable welcome wagon service nonetheless - by letting you know in advance just what you can expect before you move in, or who you really don’t want to have living next door to you.

You can also provide valuable information to those who come after you, of course - and provide a much-needed warning to future landlords, in some cases.

Sure, it’s all user-contributed information (which means you ought to take the data provided with a huge grain of salt.) But I’d rather be armed with a false warning than to find out after the fact that my new neighbor’s got a fetish for metal music cranked up to 11 at 3 in the morning, wouldn’t you?
