Going to die on this hill. The fastest read on whether an operator is sketchy is not their license footer, their bonus terms, or even their game library — it's their UI quality. Look at any operator that has gone bad in the last three years and pull up the wayback machine. The UI was always cooked.
Specific tells: laggy mobile build, inconsistent typography across pages, copy that reads like it was translated through three languages, footer trust badges that link nowhere. None of these are dispositive on their own but if you find three, the rest of the operation is rotten too. Ngl this is more reliable than any "licensed by" line.
Fight me. The UX is the tell.
