It's clear the messages are from eddies, while you are claiming drop code for around 15+ get a risk ban from the code claim. In these cases it's not because multi-account or bots have taken the code. One other thing, there should be don't have limits for claiming those codes.
Why? because you have wagering to be required for claiming a code, and the building wagering it's cost money around 10-150$ you have a chance to lose that money to building 1000-3000$ wagering based on the house edge. Unless the code it's free without any wagering and everyone can code without waggering or deposit (that's I must agree should be have some limit).
But, a code who have waggering rules required to be limits ? it's just absurd and nonsense from my perspective.
