Twitter one is a bit more iffy than you would like. Looking at it, its using your twitter username and password to send an advert. What real chance do you think that they aren't  keeping these details for reuse? You might have allowed a nice green organisation to use your account, but to morrow you could well be selling extension medication, or advertising an objectionable political party.

Any idiot can face a crisis - it's day to day living that wears you out.
