Hi,

I am working on an UC Berkeley research project to analyze wikipedia users' behaviour. As a part of the project, I am developing an application which sends a survey to a random sample of recent users. I am using mwclient code to send emails though API. After testing around 3-4 times, the email tokens are not getting generated anymore. I tried to send mails from different login user. It still gives the same error.

When I tried to send email from website http://en.wikipedia.org/wiki/Special:EmailUser. It says," As an anti-spam measure, you are limited from performing this action too many times in a short space of time, and you have exceeded this limit. Please try again in a few minutes." It has been 8 hours since and I still get the same message.

Does this mean, I exceeded limit for my ip address or for that user? When I googled it, the rate limit seems to be about 1000 api calls. I have sent mails only to 3-4 test users for 5 times maximum.

Which is a better way of sending emails to wikipedia users - Toolserver or wikimedia API? How should I handle sending bulk emails(about 100) without getting the "throttled message"?

Please help.

Thanks,
