outgoing messages blocked after sent lots of Facebook Friend invites. Also one week ago I sent 3 bulk emails.?

My outgoing messages have been blocked by Yahoo but I can access my account. It happened after I sent about 50 friend invites on facebook. One week ago, I had sent 3 emails to a large number of participants instead of using the group yahoo tool.

Facebook uses it's well researched algorithm to track use of its services viz. invites or messages.If the user uses (misuses in fb terms) any such service at an objectionable pace they come under the close eye of that algorithm and gets a warning mail.If the user doesn't stops, his activity falls in the 'ABUSE' of service policy of Facebook and they are smart enough to block that service from that account.

If 'suspicious activity' has been detected on your account, you can sign in and read mails, but not send in any way - Compose, Reply or Forward. This freeze usually lasts 24 to 48 hours, so you will just have to wait.

The most common reason for this is attempting to send to too many addresses at once. Yahoo's limits are 100 addresses in total, with only 50 per domain such as @yahoo.com, but Yahoo recommends sending to far fewer than that number at once. There is also a limit on the number of mails sent per hour (200 addresses) and per day (unknown number) The activity from one week ago might cause of the freeze on sending too - I've never read of a weekly limit, or received notice on my account, but there could be a weekly limit too.

Sometimes Yahoo is doing 'maintenance' on a particular server, which will affect service for those accounts using that one of many servers for a short while.

Your account may have been taken over and is being used as a robot 'zombie' account to send spam, unknown to you. In that case, change all your security information - a good thing to do every so often anyway. Yahoo's advice is to change your password, but there are several more security settings to change than just your password. This Help page has more information, stated clearly, with several links to clarify the steps.

FIRST, check that the alternate e-mail address/mobile phone number is still yours, under Options, Mail Options, Account Information, but then change it! (so the hacker will not be notified of the change). Check the 'Reply To:' address as well.
Then change both your password AND your secret questions and answers. Make the password a long, strong one with mixed characters! Length = Strength for passwords! Start with a sentence and make substitutions with numbers, symbols and punctuation. Go to "Update password-reset info" to change your Secret Questions and Answers. Make sure they are unchangeable, unique, and easy for you to remember.

For a Yahoo account, you can change your password at https://edit.yahoo.com/forgotroot/.

P.S. That is another reason why it is wise to have an alternate e-mail account that is NOT a Yahoo one, but has the same Contacts list! Sending from a similar username should still avoid the spam filters, or at least be recognized as 'Not Spam' by your Contacts.
