Well, I've never received trolling, but I do think I've gotten better at receiving criticism. I started writing professionally at 15, and back then I wasn't great at handling rejection, and critiques made me get really depressed. Nowadays, I can take most critiques with a grain of salt, notice the trends, and decide whether I think the consistent critiques I receive are actually a problem with my writing I should change or a matter of preference. My guiding line is usually that if things are confusing for people, they probably need to be altered unless the goal is to unravel an enigma over time with the story. if it has to do with my writing style, then it's okay if people don't like it. everyone has different tastes. I can only think of one time recently when criticism made me angry.
As for do I think I've gotten better? Definitely. It's been nearly 4 years now (will be 4 in like, November) and I've learned so much, and grown so much as a writer, developed my personal style, and learned more about properly structuring a story, moving it forward, building tension and climaxes, etc. I was basically self taught in the beginning, but since getting more advice and critiques, I've been able to use it to improve.
