It's happen sometimes, that in one line the spam occurs 1, 2 or 3 times only, and the junk percentage is 0, 50 or 66% accordingly, so this line quality will contain stars and not trash can and that's why this line is not filtered out. In nornal case when the junk percent is 100%, this line filtered out when LW 4.10.4 redisplays.
It's no use to mark this as junk.
My main problem is why this line is not marked promptly as junk (and filtered out), when in this search there is already some line marked as junk with the same result name and size.
Sometimes the name is sadly a variaton, for example asd_qwe instead of asd qwe.
