You can never be too careful these days, big brother is always watching. Especially online. For every spam bot, cam girl and scammer on the internet, there is also an account run by the feds looking to incriminate you. At the very least, you need to act with the knowledge that everything you search, post, and comment can be used against you in a court of law. 

Whether or not these 20 posts were made by federal agents, they're primed to put you in a situation you probably shouldn't be in. Fortunately, the feds aren't exactly good at blending in. Think about the number of people who give their bank account info to "single mothers near them," and it's no wonder these guys are meeting their arrest quotas. Spoiler alert, those accounts are all run by 50-year-old men, either in an FBI jacket, or in India.
