Snippet for sending sms from jajah.com, comments are in italian, taked
from a forum, it's easy to understand.
I want to give you tips, take http headers and get all things firefox
download in each page, 1/when you enter in paypal 2/when you log in
3/main page /etc, results should be like this:

#request# GET http://www.yahoo.it/
GET /
#request# GET http://it.yahoo.com/
#redirect# GET /
#request# GET
http://row.bc.yahoo.com/b?P=GoLlYNkMAwtFbx5vR%2fX%3d1187690071%2fE%3d97473701%2fR%3dithmpg%2fK%3d5%fV%3d2.1%2fW%3dR%2fY%3IT%2fF%339109684%2f%3d-1%2fS%3d1%2fJ%3d1500CD9&U=128b48k%2fN%3djXFDNkBSY-%2fC%3d-1%2fD3dTEAR2fB%3d-1

You should make everything like it comes from ie, that's hard work
otherwise ur account get limited, paypal is a multinational and will not
make life easier to script kiddies, like cj.com or others they've
professional protections against this, even with all this things script
will suffer about no javascript and no activex, I don't know if paypal
can detect javascript/activex in a hidden way, or a method to make
webservers think you have javascript/activex using a script, get a look
at http://gemal.dk/browserspy/ for how many things they can check you
against. I investigate also about Imacros that uses a browser for
automated task and visual click even with batch files, but as I mention,
it's visual and winbased, so if you want to run batch files with imacros
you've to have a working X, vmware in linux/macos will works but you
know, curl is more small/fast and not limited to scrap like imacros and
is portable, you can even run it on webservers or big software. Any
clarification of what I said will be appreciated.
