What is internet trolling or troll?

Question

Twitter is said to have vowed to tackle the problem of trolls on its site, I then thought what really is it! Is this achievable. Are they not trolling themselves by doing that

I'm not ridiculing, but did you think about it before posting this question? like honestly?

we know trolling. trolls in Zim are casualy refered to as Satanists. Contacting random strangers, making threats online, spamming, that is trolling.

All email services have a spam folder, an anti-troll mechanism. So to quote you, are they trolling you by protecting you as their user?

Next, is it do-able? well your link has a story which talks about facebook. that alone is an example of suceessful anti-trolling.

i also think asking questions like yours is trolling
