I assume you are referring to the censoring of genitals and not the removal of content.
The games in question are probably from Japan, as japanese pornography laws requires the censoring of genitals and intercourse. Apart from a few exceptions, all games from there are censored, that's just the way it is.
And since the Japanese companies don't care
much about the international market, these games will never be released in an uncensored form.
I suggest that you adjust your search filter if it bothers you too much.
