I would say it would be safer if you are, but ideally so long as you buy from an authorized reseller (who can give you all the necessary documents to prove the authenticity of your product) then you should be relatively safe. Just keep those documents ready in case someone reports you to VeRo and have your listings removed.
Remember just because everybody is doing it it doesn't always connote that you should too :)
eBay is very particular about selling brand name items so it would be best to exercise caution when you do.
Hope this helps, all the best!
