I don't think anyone other than the counters even see the spoiled papers.
Party workers, candidates, and election agents may ask to see spoiled ballots, especially if the result is close, in the hope that they can claim that the ballot should be interpret led as a vote for them.
Your vote will be recorded as a spoiled vote but that's it. The reason why won't be acknowledged by anyone.
Officially, no. Unofficially, well, there's a whole thread of women right here posting descriptions and photos of spoiled ballots. As well, what HandsOff said: it's about personal integrity first and foremost. The stickers and coloured markers and hoping candidates might notice is a secondary aim.
