It&#x27;s not just trust in strangers - its trust in the strangers and whomever may have infected the stranger with a mind-control parasite.<p>For web-sites, that includes direct hacks that make the site distribute malware, as well as &quot;malvertising&quot;, etc.<p>So that old lady next to you may actually be the gang of thugs waiting in a dark alley.<p>But I don&#x27;t think that the malware distributors are likely to choose an uncommon channel like copy-and-paste as a distribution vector, so you&#x27;re probably still OK.
