No, people should swipe left on every person they don't like for whatever reason. Remaining single is an option and might be the best for them, since that left open the opportunity to meet someone they actually like.

As long as they don't complain about being single, that is fair.

While rejection is hard, it is beter than raising your hopes up only to reject you later because they still don't like you. And trying to force it never works. People needs to feel atracted to the other person or it won't work.
