Prevent people starting an account with a name Etsy to get rid of spam?

[#1]

I have been receiving numerous spam messages daily, claiming to be from Etsy. The senders use account names like 'Etsy Support' or something similar. I believe it would be wise to prevent users from choosing nicknames or account names that include the word 'Etsy' to avoid confusion and potential scams.

If anyone would like to see how many accounts use the name Etsy in some form, here's a username search for the word Etsy. https://www.etsy.com/search/people?search_query=etsy&order=0&page=1 

I think 250 pages is the most that Etsy Search will surface so there are probably many many more accounts.

Wow- this is truly shocking!  It says at the top "66795 people found for Etsy".  I only scrolled through the first 10 pages or so, and saw probably 50 "Etsy" accounts with variations of an orange and white Etsy logo.  These accounts all look active, in that when I click on them, I can follow them or "check back later!"  

Etsy's letting this continue borders on negligence.

Each time I list an item, I get a message saying, EtsySupport wants my email so that they won't fully block my shop

Wow. These scammers are persistent.
