I've done it before. I then think to myself, what happens if they weren't actually a troll and desperately needed advice. In the off chance that they were needing help, no matter how unlikely, how many people would actually believe them? No one is going to believe them because someone yelled troll and everyone else followed suit.
I justify my answers with that. I'll give advice to people, even if it means falling into a fake question. There's always the off chance they were real problems no one would believe because they are simply uncommon.
It's annoying, but not as bad as you think. It's still out there on the internet, and people who genuinely have that question/thought/idea may come across it, and your answer will help that person. Regardless of whether the asker needed the answer or not, I reckon someone who needs that will find it eventually. I mean, thats how I found this website, multiple times googling questions and finding really old questions on here which described my situation perfectly. So it should help someone, even if it's not the intended person :)
Yes!! . This happened to me a while back. I gave a sincere answer from my heart to try to comfort the person , but it was a troll question. I realised after the asker responded to my opinion that it was a troll
You need to work on your troll sense. When something is too outrageous or extremely unlikely to happen, its always a troll. For example, 18 year old user having sex with stepmom. This only happens in pornos. In real life women have self respect and I dont know anyone who would do such a thing.
