If you are using copy scape or simillar and it shows you sites “stealing” those are not necessaraly copying even if there is a full sentence.
It is possible but in todays flooded gambling content online repetition is a result. ex. how many ways can one explain the rules of a game in a short paragraph? how many ways is it possible to explain a specific rule like “field bets” in craps?
I believe it has to be like a paragraph or whole review or multiple pages copied for a program to take hard action against affiliate.
