Is it true to sue freely?

I freely think that someone has deliberately fabricated facts and harmed the interests of the company, and has brought a lawsuit to the court.

A user named Heihua Studio Bento in Sina Weibo posted a message on Sina Weibo that the tenant had received items from unknown sources. After internal verification, the employees of the company never took the above actions, and the surveillance video also confirmed that the housekeeper did not enter or leave the unit at the time of the incident. This information is untrue and fabricates facts, which seriously damages the business reputation of the company. Our company has reported the case to the public security organ and brought a lawsuit to the court.
