The objective of this suggestion is to prevent anyone from being able to use multiple myfxbook accounts.
Having that in mind, I suggest one of the following :
1. charge a recurring monthly subs with a credit card on file (maybe even as little as $1...since it's still virtually free and nobody will complain)
or
2. a one time credit card charge of a nominal amount
Since no single person will have multiple credit cards with different billing addresses, I believe that this will almost eliminate anyone from using multiple myfxbook accounts. I guess it's almost certain that there's nobody here who are either established traders or aspiring traders who cannot afford $1/month.
In the event that either of the 2 options above don't find favour may I suggest to at least make this optional for those of us who would like to have a 'Verified Member' status prominently displayed on our profile.
Alternative ideas that will help meet the same objective are welcome... so please share if you have one.
Thank you.
