Interesting to see the amount of different inputs that people are trying. Swastikas and attempts to DROP TABLE aplenty.

you should add an algorithm to filter out the spam and make an app out of this. you could change the theme every day, e.g. tomorrow it could be "if I had [..] I would [..]", etc.

can totally see this taking off

As much as it saddens me to say this, I think this needs a CAPTCHA to keep the "hackers" from spamming it to oblivion. Cool idea, though.

its starting to seem that way.. thanks for the suggestion!

don't captcha just rate limit by ip

I like it. To limit spam, use twitter for auth and connect ideas to twitter profiles, then let people flag other people as spam - and hellban their account.

If you don't want auth, you can still just let people flag spam and hellban machines spitting out spam.

Edit: You can also use basic ratelimiting - maybe only allow 1 post per 10 seconds.

I tried testing some XSS stuff and got 500 errors, you might want to make sure you are catching encoded < > stuff

I tried

    As a SQL injection, I want a '); DROP TABLE Statements;--

And got a 500 error... you might want to look into sanitizing the data

Everyone's talking about auth to limit spam, but I think a more interesting approach is to let people click to flag spam, then train up a little naive Bayes classifier.

Did you release this anywhere else? I'd be appalled to learn all that foul language is coming from HN.

EDIT: Very sad. Nothing more to say.
