Not strictly true. If we are talking about US/Britain then text story can be
classified as 'child pornography' (or 'kiddy porn' as it was called above). As
such any software that is used to communicate can be forced to download child
pornography without your knowledge. In fact the very e-mail client you are using
can be abused in such a way. Imagine the scenario where somebody signs up to
this e-mail list and posts pornographic story involving somebody who can be
argued to be under the age of 18, your client will download this (it has no way
to contact a lawyer before downloading each message).

Frost currently uses an old system (that is going to change) which does allow an
attacker to post small bits of any files as a message. Theoretically you will be
downloading, although frost won't recognise such file as a valid message in the
end. That was one of the ways that attacks were done on Frost. The intention
currently seems to be to allow frost to communicate via Freetalk mechanisms.
