Weeeeel, I don't know what the officially official WTS stance is, but these kids (see link) at least grew up as witnesses. Their dad is an elder (or was. I haven't been around for several years so I don't know his status now) which may have helped keep them off the congregation shit list, at least initially.
My son saw them at a concert he went to several years ago. They opened for some more famous group (can't remember who). He said they were awesome. I was an active dub at the time and they, as far as I knew, were still considered good association, although their hair was rather extreme. No idea if they are still associating with the congregation any more. One would think that the hair thing would be a sore point if they are still attending meetings and such. LOL
