Where have you found this rebus? It's ok and understandable the part of your like about bitcoin. The same can be told about the fees which are low (even the miners have begun to give problems in this direction). But why the low fees must bring more scam? Which is the connection between the low fee and the scam. This cannot be understood by me. I appreciate your help in order to make more detailed comment. As for what about scammer this is easy to find. The scammer must be put in jail. If the Authorities will be able to be in touch with him.
