A recent Facebook app allowed you to generate posts with sticker figures. It’s proven very popular. Time for a reminder: Always read the Terms of Service before you agree to use an app. Just because it’s on Facebook doesn’t mean it doesn’t contain malware or have unreasonable TOS.
This particular app has attracted the interest of the Better Business Bureau because of its TOS (which apparently the company has amended).
Fortunately, Be Like Bill does NOT spread malware according to Snopes. Still, you should always be careful out there. No cute little stick figure or bouncing puppy is worth trashing your computer, or worse.
