the Wiki page for suggestive states the tag "suggests the occurrence of explicit acts or body parts [...] Also includes implied out-of-view sex."
while there are posts tagged in this manner, there are many posts not fitting into the definition, often being used as a marker for any sort of sexy content.
i wonder, for one, about the purpose of putting two different definitions (implied sex and naughty objects) under one tag, when they would be best split. for two, this tag appears to have been abused beyond all belief, to the point where the original definition is being ignored.
i do believe it leads to subjective tagging. i'd be in favour of getting rid of it.
three examples below, in order of fitting the definition, borderline fitting the definition, and not fitting the definition.
