Benignuman,
I tried posting a link to an article about it, to no avail. Try Googling “A New Conversion Scandal”. To summarize, Ariel Sharon set quotas for Russian immigrants to convert, in order to maintain the state’s “Jewish”Jewish identity. The Russians’ motivation for going along with it was for citizenship and army purposes. Their “kabalas ol mitzvos” was a complete formality and a sham. Their insincerity was evident from the outset, and they were completely nonobservant from the moment their “conversions” were done.
