Honestly I don't draw the line at all with incest, at least as far as squick is concerned, because it's one of my favorite kinks. I guess I would draw the line of interest... for me the interest in incest IS the kink, so if the strong sense of family isn't there I'm not interseted.
I don not consider pseudo-parents or chan incest, like Harry with Remus, Sirius, or Snape. Those all have their own dynamic but not incest... I don't consider Sirius/Harry incest because they're not related by blood and they do not have a long standing pseudoparent relationship in canon, Harry actually feels more mature than Sirius most of the time.
Weasleycest of all kinds I enjoy just because it's a big family which suggests an overabundance of sex in the first place to produce all those children, and then all the likelyhood of older children bathing or caring for younger etc. etc. Twincest is almost old hat to me, and Bill/Charlie is absolutely endearing to me because they are older almost by a generation to the younger children which sets them apart together. Ron/Ginny is easy to understand because of his protective/possessive dynamic with her... other pairings would be new and interesting to me... I have never read any Weasley parent incest but I would be interested.
I guess the whole thing with me is, I'm interested in incest when it explores when loving affectionate family relationships cross over into sexual affection. For that reason I'm pretty much mostly concerned with Weasleycest. Pottercest is too AU unless it's necrophilia, and sometimes I'll read it just to get a taste of that kink. Blackcest just doesn't interest me at all because the tight family dynamic isn't there. Incest in an already dark affectionless family is uninteresting to me because it's just another form of already prevelant abuse/neglect so it doesn't really stand out.
