I tend to ignore and/or block without a word people who remind me of someone who wronged me. They remind me of that particular person so I get immediately distrusting and on the defensive.
For example, if guy X from town Y really wronged me, I start avoiding all guys from town Y even if they have no bad intention and are nice with me. Likewise, if girl Y from country X wrongs me, I'll have prejudices for all women from country X and more oftent not shut them early on even if they are being legitimately nice and helpful.
