Social media platforms such as Facebook, Twitter, Instagram, and LinkedIn have changed the way we communicate, share information, and connect with others.. You said it write that 18 years age is correct age to use but now a days children are using mobile . My daughter who is less than 2 years old use mobile phone and watch cartoon channel and after few years surely she will into social media which is wrong I know but what to do .so you have mentioned very tricky points. Good luck for the contest.
