If I draw a line

Then I may have a sign to not cross.

If I draw another line... I might accidentally draw a cross unintentionally.–suddenly people think its okay to cross me.

If then I draw another line, I may accidentally draw it to seem discreet or blashy because of they're perspection of a cross with multiple lines... or how I was actually trying to type this being an different understanding.

if I continue to draw lines the lines are there the ideas are there but depending on what I need It will be understood or at least should because; draw enough lines and it's just a bunch of lines? But what if I want it all to be hidden symbols or to avoid hidden symbols.

What am i?
