Im not sure it’s in writing but what problemaddict wrote is true. Years ago, maybe a year or so after facebook came out, my wife and I had a “shepherding” call and were strongly counseled about being on facebook. My MIL lost her pioneering status because she refused to delete her account. I lost my “privileges” until I deleted my account.
In the years that followed, they loosened up a little. Each congregation has their own stupid little things to pick on.
