I will add your comment in my post….yes they were generally expelled for:
1. Coin clipping in England (modern term: Bank Fleecing)
2. Using goy children for sacrificial purpose such as Simon of Trent (Modern equivalent: Using Gaza children as shooting target).
3. Usury / exploitation of poor (Modern equivalent Zionist controlled IMF and exploitation of undeveloped countries)
4. Abusing Christian (goyim) religion (modern equivalent of Pamela Geller)
