the answer can be in my opinion social media is little bit safe while going with these restrictions with privacy if we doesnt put any posts and doesnt update any information and even doesnt update any status too it seems little bit safe bcoz no information is real according to our knowledge
I do not agree, in my opinion most social media platforms aren't concerned about your privacy, as a matter of fact, there are even created to somewhat ensure you do not have a private life by linking you up with friends and people who may know you, just as facebook does for example. And mind you that it doesn't even matter if you post or not, the information they request from you upon registering is usually enough for them to know who you are.
but if scammers and hackers enterd it seems worst and totally unsafe .if they doesnt enters all will be ok
There is no way to prevent scammers from joining a social media platform as there is no way to identify them as scammers when they are registering, the onus is on the user to do their research, verify who is communicating with them, and shun greed.
