You're a new seller with low feedback selling high end items. You are a target for scammers. Your listings were probably removed due to not being allowed to sell that brand on eBay. The high end brands regularly check eBay and demand listings of their brand to be removed.
Even though you are selling second hand, which you should be able to do, and plenty do, high end brands are considered to be fakes thanks to the chinese pumping out mass produced rubbish. If the rights owner sees them, eBay is legally obliged to remove those listings.
Now, in regards to overseas buyers. You need to set up blocks so they can't buy from you. Just not offering international postage isn't enough. Click up the top left where it says "g'day your name" then click account settings. Next screen click site preferences from the menu on the left.
Scroll to postage preferences and click show on the right. Look for "exclude postage locations from your listings" and to the right of that click edit. Tick all the boxes except the PO box on the next screen, then tick to apply to all current live listings and apply.
Hit the back button to go back to site preferences. Scroll down to buyer requirements and on the right click show, then edit. On the next screen:
Buyers with unpaid item strikes, set at 2 in 12 months.
Buyers in a location I don't post to, tick.
Buyers with policy violations, set to 4 in 6 months.
Buters who haven't gone through phone verification, tick.
Apply above settings to active and future listings, tick.
Don't allow blocked buyers to contact me, tick.
Submit.
Hopefully that stops the Nigerian scammers.
