That's pretty correct... I actually found an online article in Ukrainian/Bielorrusian reporting this ... It explained that one or both of the brothers were personal trainers in a local gym at a time when they were filming (reasonably tame) body worship videos and would sometimes end up jacking off (these are the very early ones) ... The article said somebody recognised the gym in the video and reported them ... they got expelled and they had to leave the town they were in.. I think that's when they ended up in Belarus (i think originally they were based in Ukraine). The article never mentioned sexual content, just inappropriate usage of the location/inappropriate videos.... I used Google translate to read the article, so I'm pretty sure it was all genuine..
It's funny cos since they have moved to Belarus they have connected both with Stas Mochailo/Superstas (the really big, tatted bodybuilder we see in the more recent videos) and with Romeo/Roman (the slightly smaller bodybuilder with deep pale blue "wolf" eyes) and the content has become much more explicit... Yet we think of Belarus as a country with strong censorship and homophobic culture.. just shows that in those types of countries so long as you keep under the radar, you can do pretty much what you want ...
