They're no longer active in the community, but when I first joined the Arena a total stranger sent me a PM asking if I wanted some ponies. I was told they were mostly baity G1s and some accessories. At the time I only had a small handful of ponies, couldn't afford more, and was going through a rough time postpartum after my son was adopted.
The box took a while to arrive and I think it actually showed up at our old house the day we moved because grandma had to forward it to our new address on the other side of the country. But after all the waiting, it was so worth it. I vividly remember my excitement and happiness as I pulled pony after pony after pony out of the box. It was packed completely full, way more than I ever could have guessed. Almost half of my G1s are still from this box and I still have every single pony and accessory. One of my favorite ponies, my baity cancer spotted Moonstone, was in there. My extremely baity Baby Firefly, my little travelling companion for so many trips, was in there. I discovered my love of baity G1s and G1s without tails from this box, which still shape my collecting preferences today.
I don't think I ever spoke to this person again and a lot of bad stuff (like scamming) came out about them later. While those actions are inexcusable, I'll still forever be grateful to them for showing so much kindness to me when I was a newbie. Their selfless gift meant the world to me and still brings me so much happiness 8 years later.
