Is there a saying that Spring Festival couplets are posted backwards?

It doesn't matter if you post couplets. Few people go to a dead end to comment.

According to traditional customs, in order to increase the festive atmosphere during the Spring Festival, couplets are usually posted. Moreover, because ancient China people attached great importance to the atmosphere of the New Year, especially the elderly and children, they would choose to reunite with their families.

Besides, even during the Spring Festival, people can still discuss with each other. There are many old folk customs, such as sweeping dust, eating New Year's Eve, hanging firecrackers and so on. It is said that this custom has gradually evolved into a custom.
