Supernatural Story Finders

I don't have any recs for this, but wanted to ask a related question. As a new author to this fandom, should I be putting bottom!Jared, bottom!Sam etc in the header? It honestly never occurred to me with the first story I posted and I never realized how divided the readership could be on this issue. If someone actually doesn't want to read a bottom!Jensen story, for instance, I'd hate for them to get to the end of one of my stories and have it spoiled for that reason. Bottom line (no pun intended): would you rather see that straight away so that you know? Or do you think that might ruin it for some people?
