Words currently perceived as bland may tomorrow connote a far less innocent consensus interpretation.
Language constantly evolves and is never static and forever set in stone.
We must be very cautious not to discourage creativity and valid change. I am not exaggerating in the least when claiming that blocking software literally inhibits our ability to reason and communicate with each other. This could result in discouraging many to use words that even remotely possess a double entendre sexual meaning. There might be a justification for blocking software designed to protect children and certain business environments. This seems to be the main excuse presently to justify such software.
