Online gaming.

Is online gaming safe? 
Some online games may be are safe and some may not be safe.
I think, online gaming gives rise to too much of addiction towards it which makes a teenage, children loose their sense that it can cause a threat to their life.  Online games make a child or teenage do whatever they instruct.  The most deadly game is : THE BLUE WHALE  ,which caused 150 death till now,which starts giving the challenge if drawing a whale on a paper at the first level then leads to death challenge at the last level. There r similar games to this game which cause damage to children and teenage.  I think online gaming should be certified and should have age limits,so that everyone cannot handle,and lives can be saved.  Too much of addiction towards something can cause damage, children as well as other users should know.  Love your life, live your life. 
Thank you.
