To give you some insight into why we might add prefixes that don't seem to make logical sense, merchants which are treated by the financial industry as high risk get monitored for compliance. A lot.
A merchant will be monitored by their own bank, by their payment processors, by those payment processors banks, (of which there are likely to be several,) and sometimes even the banks that those banks partner with for cross currency settlement.
All of those banks will have their own slightly different interpretation of the rules, and their own list of stopwords they don't want to see.
Some compliance teams will take the time to look at the context of a stopword they find, others will just fire off an email requesting that it is removed, which then takes time and effort to resolve.
We know the performers are not actually related. You know the performers are not actually related. The banks know this too. I don't think that a slight amendment to the title is going to seriously damage the ability to suspend disbelief.
But it will stop us getting pinged by the crawlers; it means we can spend that time and energy on delivering more content instead.
