if you take a look at this
https://www.bustabit.com/license.txtyou will know which site that buy the license from bustabit, and for ethercrash case it seems they buy from bustabit.
Thank you for the link. I forgot about that URL. Yes it seems ethercrash did buy a licence.
What is confusing though is how the Bustabit and Ethercrash websites seem almost identical down to the layout and even chat plugin. I thought licences were regarding the crash software only so how did ethercrash end up getting a clone of Bustabit?
Devans sells the code of old bustabit v1 which had the same design but with Bustabit right now, Devans just took the UI and made it look cleaner.
So did Ethercrash, they took the old bustabit look and made it look cleaner, other sites like bitcrash.us ( not recommended playing there ) has the actual exact same design that was use for Bustabit back in the days.
