Earl was a very stupid and naive kid and made a mistake, he'll have to cop some punishmentfor that. But there is no doubt he had his trust abused by Dank and possibly the Panthers. It shouldnt end his career.
1-2 year ban seems about right to me, serves as a sevre warning to athletes that ignorance isnt a defense, but also takes into account the circumstances which led to this. Penrith's involvement in this should be heavily investigated. If Earl is right and they both recommended him to Dank and paid for this treatment, heavy fines and sactions should be handed down to that club.
Edit: I am not saying that is true, but the allegation has been made and must be fully investigated. If proven correct, it's pretty damning on the Penrith club. But it could all very well be a load of shit designed to garner sympathy for Sandor, either way it needs to be investigated.
