Honestly, I would not be too concerned about it. Its your money, why pay them right? Specially since its a stealth account. I doubt they'll go as far as IP address to track you down.
I can speak from experience in paypal tracking you down. They act all tough and scary. but they aint shit really.
I was selling digital goods years ago on ebay. before having tracking numbers was such a big deal and so many scam artists on there.
anywho, i sold in game items for an MMORPG on ebay, was paid via paypal, and made bank. least in my mind i did, being i was only 15 and was making as much then while in school, playing sports, homework, and hanging out with friends as i do now working 60 hours a week. god i miss those days, paid to play games. ah...twas the life lol.
anywho...since i sold digital goods, transferred in game, there was no shipping. because i didnt ship anything, i have no tracking. no tracking means no proof of delivery. welp...one of these gamers got smart on me and decided they were gonna report me for never delivering. they opened up a claim with paypal. paypal asked me for proof of shipping. since it was online, i had nothing. at this time, it wasnt against ebays TOS to sell digital goods. but for some freakin reason, it was against paypals TOS. the rep i spoke to said that ALL purchase transactions are to be for physical goods, and that the seller is required to provide proof of shipment if requested to do so.
obviously, i couldnt prove jack to paypal. and it was a buyers market. paypal ALWAYS favored the buyer. i lost the claim. $2,000 worth of chargebacks. They drained my paypal account, taking away $1300 straight up. that was all i had in the account at the time. What was strange, they attempted to obtain the remaining funds via the back account linked to the paypal account. thankfully my back account say that as strange, and put a hold on that transaction until i could confirm it. which i told the bank hell no, dont give them a penny. and they didnt.
Paypal still wants their money from me. but they shall never get it. they have threatened to take me to court over it. i have since then opened up 3 new paypal accounts, new banks in new cities. the first bank account was same name same city, only a few months later. of course they froze this account, and took all the money from it. i was careful and drained this account as much as possible. they only got maybe $100 from me on this account. second time i used a family member's account. not sure how they linked this one to me, besides last name. different computer, different house, different ip address, different ebay account. everything was different, but they linked it to me. froze the account, took over a month to get the funds out. they shut this account down. only thing i was allowed to do is deposit the money in the linked back account. couldnt send or receive payments of any sorts. the third account was a few years later, under my name and in a different town. same thing as account two, but not much money was in it that time.
point of this is, they have been chasing me down for 8 years now. and they wont get anything more from me either! i refuse to pay them. i've gotten letters from them saying to pay it. they constantly called me, non stop, at the most inconvenient hours, telling me i owe them $XXX.XX and if i dont pay it they'll sue me. i got letters from collection agencies. and i got notices of paypal bringing up charges against me. somehow they happened to obtain a few of my numbers, and some of my previous addresses as well. calling and mailing me.
but i'm still fine. 8 years and going. if it got serious, i would fight them on the fact that they allowed a minor use their site. but it hasnt come to that yet. and i do not plan on giving them a penny more of my money. screw paypal.
so in summary, i'd say you'll be fine. stealth account, i really doubt they'll do much to track down the real you. if you're paranoid bout it, or believe in karma, then it may be best to pay it off if you can afford to do so. if you were me, i'd tell paypal to go to hell and give them the finger as you smile at them. maybe send them a picture of your new account with some other site and write a nice and loving letter about how much better this other company is compared to how much paypal sucks. but thats just me.
i do not claim to be a lawyer and the above is NOT legal advise. They are opinions, not facts, based on my thoughts and biased feelings towards paypal. Do not take my words as legal advice, and seek professional council from a registered law practitioner if you feel the need for legal advice. and above all else, screw paypal!
