I'd say getting 0/0 limits right off the bat basically means you've given ebay reason to be suspicious of you. They haven't linked you to a banned account or you'd be indefinitely suspended, it's just that somewhere in your methods you're doing something they think is common among stealth users, so you'll have to change that up.
The problem is that it could honestly be a variety of things. As mentioned above, the phone is a great place to start. Just buy the cheapest prepaid phone you can find. Most even comes with free minutes so you wouldn't have to spend anything beyond the initial purchase. Try using that along with your current methods. If you still get 0/0 limits, start changing things up one by one until you find the problem. You don't even need to verify the paypal first before turning it into a seller account (I never do, especially now with working vbas being a rarity). Maybe try switching up your IP service? For example, if you're using a VPS to create the accounts, try tethering instead. Or if you're already tethering, try using a hotspot, etc.
For what it's worth, I create new accounts almost daily with a fake name and only got 0/0 limits once recently (though that was for an entirely different reason).
