Same artist with two IDs

[soheilpro]

These two artists are the same but have different ids. Is there some kind of redirection going on?

https://open.spotify.com/artist/1yaQlQCA4vkEq2oyv4KNVJ
https://open.spotify.com/artist/7mFGOWJEkdlJBCXcJ5EWi9 

If you call the /v1/artists endpoint with the first id, you'll get the second artist:

curl "https://api.spotify.com/v1/artists?ids=1yaQlQCA4vkEq2oyv4KNVJ "

{
   "artists": [
      "id": "7mFGOWJEkdlJBCXcJ5EWi9"

   ]
}
