So, I added a whole bunch of house numbers while going to check the name of a park. Turns out the "park" (basically a grassy zone) was next to a community garden, as I has suspected (though I'm still trying to figure what the "BP" stands for...). Haven't added much else because it's quiet residential streets, so there are no phones, post boxes or whatever. Will probably need to go back and double-check for the way the alleys are laid.

On a totally different topic, who should eb alerted when it comes to this silliness? The system purging accounts probably could use a revision because if deleting an account does NOT actually removes the offending links, there is no incentive for spammers to stop. Wouldn't a cap on number of links be simpler to implement?

ETA: Now that's an improvement ^__^
