It may not have been removed, it could have been moved.
If it has been deleted, then, you might want to read our Guidelines about the types of sites we do not list, and see if you can find a reason there.
Otherwise, no, there is no way to find out why it was deleted, no way for you to get it relisted, and no way for you to convince us it should be listed, which is one of the possible reasons we don't do status checks anymore,
, they just lead to more questions that we won't answer.
Site suggestions get listed at our sole discretion, we're not a listing service.
