I haven't really had any huge mistakes besides donating my FQD one time. A friend of mine accidentally fed my BGC to grarrl. This was back when they were worth a lot more.
Not sure if this was an mistake on my end or my sisters, my parents forced us to share one neopet account between the two of us. Over the course of about an year we had saved up about 980K. My sister bought Orb of the Dark Faerie for 750K in the trading post thinking it was worth millions/ hidden tower item. She came to me crying, any way neopet scams where common back in the day. I set up a weebly neopets login page and sent it to the person that scammed my sister. Stole everything from the scammers account and in the end got both account frozen.

There used to be a thing you put codes into and it gave you codestones.
I got the bright idea to make a lot of accounts and get codestones from all of them to make a crap ton of NP.
By the time I did it on the 3rd account, my main and all 15 accounts I made were chain frozen.

A long time ago, I responded to someone's mail from a separate account than my main. To this day I have no idea how I fucked up that bad...

I was so desperate for the game avatars that I downloaded a Firefox extension to get them for me... this was way before I knew about cheating. My account was 100% legit and I was heartbroken when it was frozen.

I won Faerie Caverns Stamp and accidentally discarded it.

I stored items in my Shop and went to remove 32 of the same Unbuyable item from my shop only I accidentally priced them at 32 neopoints. Took an over 7million loss which is alot when you're playing legit :/
i think my biggest mistake was pricing some items in my shop because I sometimes use it as an sdb (IDK why)
One of them was a really rare tcg item. Priced it for a couple 1000nps. Yea don’t know how many times I called myself an idiot that day lol.
