What is the difference between Trolling, and having a laugh?

To some people there's no difference.

I've no problem with funny questions or answers. I love trying to lighten people's days!

Others though take YA as some sort of sacred place where you have to answer everything with a dour expression and a clipped and precise answer.

Trolling is defined as creating discord on the Internet by starting quarrels or upsetting people by posting inflammatory or off-topic messages in an online community. Basically, a social media troll is someone who purposely says something controversial in order to get a rise out of other users

trolling is insulting and laughing is having fun... i guess..

Trolling is to have a laugh at somebody else's expense, like pushing an old lady down stairs for your own amusement. The essence of humor is the unexpected, which is not viciousness.

I'm having a laugh and you are trolling.

Its a bit like I am careful with money - you are stingy

Having a laugh is not so negative as trolling

Troll all you want on some other site. This site is for those in help, over something as simple as "What is a safe temperature to cook pork?" to "My granddaughter just swallowed a bottle of pills" (both actual questions I have answered), they need someone who can help to find and answer their question quickly. Those seeking to answer questions also have a limited time to find someone they can help. When much of that time is wasted scrolling through childish trolls, no one here is laughing. Grow up.

Trolling is an annoyance whereas having a laugh or laughing is being happy or joyous.

Because trolling means to laugh at SOMEONE ELSE'S EXPENSE.

"Trolls" take it too far, they go online with the intent on hurting someone, they sometimes target people and keep doing or saying harsh thing to the same people. Trolls don't stop, whereas "having a laugh" normally knows when to stop

Having a laugh is great. But the trolls on here hurt people.
