Strange accounts

In hearthstone I’m meeting dozens of accounts with nicknames made of random letters with very basic decks, in my opinion they are fake accounts created only to test an AI that plays for you

Most likely bots farming gold, you can report them when you encounter them.

Wild?

there where a bunch of bots with very basic cards for 2 Days, with names in either asian chars or XXXxxxxXxxXXX for names, they lasted about 48 hours before I outranked them or they all got banned.
I cant tell you how many times I saw coin to play a 2 mana 1v2 or 2v1 stat stick on the first turn.

Yes, I noticed that too. Recently, there are a lot of such accounts. Approximately, 80%.
I think that if you rise in the rating, there will be fewer of them, but before this was not the case even in the middle ratings. They always attack the hero regardless of any other creatures on the field.
