Picasa Helping Spammers

Without any CAPTCHA or spam prevention algorithms, spammers are taking advantage of the flaw in its album sharing feature to send out spam emails. Spammers send out album invitations together with a whole chunk of spam message and could easily get around Gmail's spam filters and arrive in victim's Inbox as the sender is from a highly trusted source - a Google domain.

There have been similar reports by Gmail users in the Google Blogoscoped Forum. And spammers have also eyed Picasa's comment system to distribute spam.

It is clear that the next mission for the Picasa Team is to find away to avoid spammers from abusing its system.
