Some ponies appear to be under the impression that Princess Celestia practices this. However, as far as we know, she does not.
Nightmare Moon's vow to bring about The Night That Never Ends was because her pony subjects enjoyed the daytime her sister brought, but didn't appreciate the nights she created. Creating a night that never ends means depriving everyone of the sun, which means no crops grow, nobody gets any natural heat, and everyone either freezes to death or starves, meaning that Nightmare Moon would have inadvertently killed everyone just to get more attention.
Applejack once called Mr. Beaverton Beaverteeth a nuisance. His response? Building a dam to flood Applejack's home, followed by using several swear words against her. Luckily, Fluttershy was able to convince him to stop.
Fluttershy may have gone a little too far when applying her assertiveness training in "Putting Your Hoof Down".
Magic Duel is all about this. Twilight exposes Trixie's lies about her having defeated an Ursa Major (which has the unfortunate effect of ruining Trixie's career, but Twilight had no intention of doing that) and shows herself to be more powerful than "The Great and Powerful Trixie". Trixie returns with a magic-boosting amulet and humiliates Twilight's friends (and actually mutilates Dash and Pinkie magically), defeats Twilight, and banishes her from Ponyville. She then takes over the town, enslaves the ponies, tortures Snips and Snails by making them drag her around on a wheel-less wagon, and generally goes Caligula. It turns out that most of the crazy is caused by the evil amulet, and losing it makes her regain her senses after a while.
It's also revealed that similar disproportionate retribution happened to Trixie herself. Since a single lie told to shut up hecklers lead to her entire career and reputation being completely ruined, an apparent stint of poverty and homelessness and being forced to do manual labour to scrape a living. While revenge against Twilight is unwarranted, as she didn't really do anything, its hard not to see how she could be frustrated by her bad fortune even before putting the amulet of insanity on, nor is it easy to call her revenge against all of Ponyville unjustified when Ponyville residents were following her around to vandalize her cart and bully her. And unlike Twilight's situation, which goes away once Trixie has been stopped, none of that has been changed...
This was actually the main driving point of "Lesson Zero"... in Twilight's mind. She ends up freaking out, thinking that because she forgot one letter to Celestia, she was going to get sent back to Magical Kindergarten.
In "Gauntlet of Fire", the dragon Garble decides that, if he can become the Dragon Lord, his first action will be to raze all of Equestria to the ground due to his hatred of Spike, Rarity, Twilight Sparkle and Rainbow Dash, who humiliated him once.
Starlight Glimmer resented the very existence of Cutie Marks because her friend Sunburst's Cutie Mark which supposedly marked him as a talented mage separated the two of them since she didn't know that the real reason he never contacted her again was because he found out he was actually an Inept Mage with almost no real magical power and he was too ashamed to let her know. So she came up with a spell that steals Cutie Marks, suppressing the talents of ponies, and brainwashes her village into thinking this is the right way to live. She also tries to brainwash the Mane 6 with hopes of spreading her twisted doctrine to all of Equestria. When that fails, she spends the rest of the season obsessed with revenge and uses an extremely dangerous Time Travel spell to ensure the Mane 6 never get their Cutie Marks, not knowing just how badly this would screw up the past, present, and future of the world. Again, all of this was because a friend moved away.
In the episode "Rarity Investigates," Rainbow Dash is accused of sending Spitfire away so that she could take her place in the Wonderbolts' air show, and is told that if she can't prove she is innocent, she'll be kicked out of the Wonderbolts for good. Luckily, with a little help from Rarity, Rainbow Dash finds out that the real culprit was Wind Rider, a retired Wonderbolt who Rainbow Dash greatly admires. Why did he go through all the trouble to frame Rainbow Dash and make sure she got kicked off the Wonderbolts? Because he was afraid that she would break his flight speed record.
. And unlike Twilight's situation, which goes away once Trixie has been stopped, none of that has been changed...
