Just an FYI-

While I agree you shouldn't give it out without caution, just be aware that it is a very, very common practice in other parts of the world.

So if someone from the UK asks for it, it's not necessarily because of any nefarious intentions. They might be as unaware of the rarity of it here in the US as most Americans are of its ubiquitous use overseas.

And unaware of the additional fees that might be involved here.

So, yeah, PayPal is the way to go.
