How about setting the bar for posting/upvoting at "Actually fooled me".
The explicit guideline would be:
- Post/upvote online if you think it's legit after reading the content. It's OK to upvote even if you realize it's fake later (e.g. from comments) - this is considered timeshifted voting not a violation of the guideline.
- Don't flag/downvote on the sole basis believing it's a joke. Of course flag/downvote as normal for any other reason, e.g. it sucks.
- No addition restrictions on commenting, in particular mocking the OP is perfectly OK [edit: so long you abide by the normal community guidelines of civility etc]
The double email entry makes perfect sense if you accept the following base assumption:
The designer of this form is the Kwisatz Haderach! He sees all of your potential futures laid out before him, almost as if they were lines on a whiteboard. To him you are not a person filling out a form, you are a quantum of potential revenue in a treacherous maze of possible outcomes. He is afraid, because he sees many many futures in which you simply cease to exist - your potential collapses to $0. There are a precious few paths where you survive this peril, and every single one begins with you typing in your email address correctly. A password can be recovered, but you can not.
It other words, this form is for quanta of potential revenue, not people. Don't forget the quanta pay the bills though.
