Hi,
I cannot think of a solid usecase but I think that sending greetings is a probable spam-prone area. I noticed to send a greeting you just need to login to your account and type this in the browser:
http://demozzz.com/dolphin7b/greet.php?sendto=<user_id>&from=<the_spammer_id>&ConfCode=
No authorization or captcha code is required.
So a spammer can create an account, login and just use a script and have this url in it:
http://demozzz.com/dolphin7b/greet.php?sendto=<user_id>&from=<the_spammer_id>&ConfCode=
And then all he needs to do is to increment the user_id count and fire the request again to send greetings to a different user. So imagine how easy it would be to SPAM the whole community forget about server load issues.
What do you say guys???
