Personal data privacy at risk
Actually is not safe enought, the exposition of personal information in social networks always carries a risk, so it's better to be conscious about the type of content that's shared. Personally, I only share cat memes or shitpost in facebook, no personal photos, no entries of any kind, ONLY MEMES and I don't accept any friendship invitation of people I don't know. About instagram, I don't have instagram or whatsapp so I comunicate with my friends only with smoke signals. Security carries sacrifice.
