rephrasing bit of tutorial wording #340

Please change:

"The scheduler does not allow that one user will submit two or more answers for the same task (for anonymous users PyBossa uses the IP)."

to

The scheduler does not allow the same user to submit more than one answer for any task (even 'anonymous' users who are not logged in, are recognised via their IP address).

...but many people I know have dynamically assigned IP addresses. If they anonymously complete 10 tasks one day... isn't there a danger that if they come back the next time (with a different IP address) and don't login they won't be recognised and have opportunities to do the same tasks? Just a thought. I guess the idea is that if they come back more than once they would probably get an account & login.

Hi,

Thanks for the rephrashing :+1: now is more clear!!!

About the IP addresses, I've a dynamic IP and usually what ISPs do is to cache that IP for your router, so you usually have the same IP for long periods. However, as you have mentioned, if someone gets another IP they will be able to trick the system. Moreover, using an anonymous proxy will be even easier :-) Any ideas about how to fix that?
