Which developing countries? I thought that many of those countries were either tied up with 'real', physical crime or just wouldn't care about internet stuff all that much. Lots of sketchy websites (like lots of piracy-related stuff) are hosted in countries where legal consequences are unlikely, even if it's illegal on paper. I can see how the more authoritarian countries can be going after social media posts based on grudges, but I'm wondering about which ones actively practice it - I don't know much about it.
UK and Germany come to mind where the police/law will go after people for what they post.
That's just for developed countries. Consequences are worse in developing countries.
