If you erase all your online traces, there are almost zero chances of someone looking for you, but at the time I write this comment, there should be no chance of accessing your Dread account.
Update:
I am doing well. Opsec is good trust.
Credit card got declined for being expired.
The other one wasn't credit (even though I requested two credit from a supposedly reputable vendor). That one wanted pin. Wouldn't let me skip it and 0000 didn't work.
Just walked out the store. Whatever. Still learning.
