Wow, that fucking sucks bro. I checked out the instance, and your name (and iconic profile pic) was on the top of whatever they call "All" over there.
If it takes off and you need to create a new name, please keep us informed. Your memes are vital lifeblood to the fediverse, lmao (but seriously everyone here loves you and we wanna keep in touch).
Don't fuck with school computers, it's not your property. If you wanna mess around with Linux, I will literally send you my laptop. Don't get in trouble when it's not necessary, especially because it seems like your reasoning for this whole thing is, "they left a door open", like my cat every time I open the refrigerator. And just like my cat, you will be tossed out.
Looks like it's too late to sign up, I just tried and it kept telling me to "verify that [I'm] not a robot" without giving me anything (like a captcha) to do so.
I'm in Texas. I've been cashier in multiple roles, between my entry-level stuff and sometimes having to fill in. I don't know about the laws elsewhere. Every payment system I've ever used had a way that you could split payment, and usually if it was a debit card of any sort, it would just take whatever was left in the account and you'd have a remaining balance, payable any other way. That said, if anyone is ever thinking about getting me a gift card, I just tell them to give me the cash equivalent, it's more useful than cards.
Ah, I get it! The concept behind "federation" still escapes me sometimes lol. Good to know you're still rockin' on a new platform!
