rss throttling

i don’t think i mentioned this when i implemented it last weekend, but ip addresses that now poll one of my scraped rss feeds more than once an hour will find themselves blocked from polling for the next hour. (the limit isn’t really quite an hour, but in that neighborhood.)

the fun part is that it is a rolling block — the second attempt before the required time has passed results in the timer resetting. when i decide to be truly evil, it will start returning an rss feed with something other than the content being requested. (right now it gives a 403 response with a simple text message.)
