But many users won't use regularly the same email address they have for PayPal, I know I don't. How would you overcome that complaint?
And cookies are easy to delete, so that's not a good option, unless you provide such an improved experience thanks to the cookies that they would hesitate to delete them, but you can hardly achieve that in 3 days.
Then there are Flash cookies, which most people don't know how to delete, you could try those, and there are browser footprints that you could use to identify users. You'd have to read up on them to find how they're used, I don't have any experience with them.Statistics: Posted by Cristián Lávaque — May 15th, 2011, 11:51 am
