Since I received an X Premium *(worst name in existence)* subscription for free, I can create ads on Twitter. However, the point of an ad is that you're supposed to pay for it... right?
Well, as it turns out, Twitter just overlooked that. I have my payment method set to a $25 AMEX gift card that I received last year as a graduation gift:
And according to the Twitter Ads website, I've spent $200.47:
But that's not what the AMEX gift card balance website is saying.
There's no record of Twitter anywhere in the transaction list, either.
Normally, when you spend money on advertising on Twitter but don't actually pay Twitter, it goes to your balance.
Nothing.
I'm not entirely sure what's going on, but I think I may have just somehow slipped past Twitter's system and got myself unlimited free ad space.
