I don't understand why Russia simply removes any tax breaks they get, remove their status as a religion and merely classifies them as a business (which they are).
Then go all out in organising an official enquiry into their child abuse problem, like CARC. An inquiry Into the shunning of minors, the illegal pressure they put on members to refuse blood, & Watchtower orders not to vote. All on pain of shunning & DF/DA.
All of these things are legit methods of bringing the organization terrible publicity, driving away converts & making Watchtower in Russia's life difficult & costly.
They may possibly even force change on some of their behaviours if heavy financial penalties are at stake.
