Blocking VS Changing user name

[carolinsiazo_0]

Hello, 

Is there a reason why EBay doesn’t have the option to completely block someone on the site? 

Its very uncomfortable knowing I have someone watching over me.
Even though they cannot buy from me since I was able to only block them that way. Has made me less as a seller since last year.
The only option I was told was changing my eBay username. Changing my username what would I lose (reviews) ?I’ve blocked this person from all areas from social media to emails and changing my number however, eBay is the only place that makes me feel I have to hide. 
Would changing my username erase my history as a seller & buyer? 
Would this have my followers unfollow me or would they still be able to find me with my new username since they’re followers?

On eBay, anyone that knows your username can search for your items for sale and find them. Users do not need to be signed in to search, so even if you were able to block a user from seeing your items, the user could simply sign out and search again to avoid that block.

Changing your username will not affect your followers; they would still have you as a saved seller under your new username.

However, users that only know your old username may have trouble finding your listings; users that have your "items for sale" bookmarked will find that the bookmark no longer works to find your items, though individual listings that were watched or bookmarked would still be watched or bookmarked, and the new username would be findable that way.

You would not lose your account history unless you created a new account and deleted the old account.
