Abstract: Using a technique due to van Mill we show that each compact ccc $ F$-space of weight greater than $ {2^\omega }$ contains a weak $ P$-point, i.e. a point $ x \in X$ such that $ x \notin \overline F $ for each countable $ F \subset X - \{ x\} $. We show that, assuming $ BF(c)$, each nowhere separable compact $ F$-space has a weak $ P$-point. We show the existence of points which are not limit points of any countable nowhere dense set in compact $ F$-spaces of weight $ {\aleph _1}$. We also discuss remote points and points not the limit point of any countable discrete set.
