Snapchat's terrible month just got worse.

The app apparently has a big spam problem and its users are complaining about a flood of Snaps, disappearing photo messages, from strangers. On Monday, the company apologized for the spam in a blog post.

"While we expect to minimize spam, it is the consequence of a quickly growing service," Snapchat wrote in the post, linking to an April 2013 blog post where they addressed past complaints about spam messages.

Though Snapchat users can not presently report spam -- you can only block after you get it -- there is an easy way to ensure you don't receive any strange, spammy snaps from strangers. Simply go into the "Settings" section of the app and change "Who Can Send Me Snaps" from "Everyone" to "My Friends."

The quick apology shows Snapchat may have learned its lesson after the app experienced a massive data breach on December 31, when a hacker released the full names and phone numbers of 4.6 million users.

The company addressed the security vulnerability by updating the "Find Friends" option so that new Snapchatters need to verify their phone number.
