Well that’s not good…
Can you please confirm the account name, I’m not able to find any accounts with the name “asd dsa”. Did you change the account name to lrCvB1517?
Here’s some info on the hacking attempts (and successes unfortunately) being carried out by a group of Russian hackers, and what Epic is doing to combat it. There were large “dumps” of usernames (or email addresses) and passwords posted to some hacking forums a while back, if you use the same password for other sites, such as unrealengine.com, the hackers are able to get in. I’m not entirely sure why they would create an account for you, they have been hacking into accounts and charging people’s credit cards or Paypal for Fortnite V-Bucks (in game currency), this is the first time I have heard of an account being created. Could you please post a screenshot (or a copy of the email text) of the email your received that includes the full email address so we can see if it is legit?
If you do use the same password for your email on any other site change those passwords AND your email password immediately to prevent more accounts being hacked!!! See the security bulletin I linked above for more details.
To delete your account please contact Epic Account Support by filling out this form. It says Fortnite, but it’s for UE4 support too, just select “PC/Mac” from the Fortnite Game Platform combo-box, select a random Game Mode, and then use “Accounts” option for Game Issue.
Make sure to include all relevant information, including a screenshot/copy of the email your received. I am not sure whether they can blacklist your email, but mention that in your post too.
Please note the support staff are very busy so it may take a few days to receive a response. They will reply back to you by email as soon as possible.
