I can't read it clearly. What the landlord means is that someone pretends to be your name to seize your customers online, and at the same time, there are also acts of slandering you, right? If you open the baidu promotion (which is the kind of bidding), your company has brand protection in Baidu, and others can't appear your brand and company in the bidding promotion. You can go to your Baidu marketing assistant for this. If you are posting in a forum like Post Bar, I'm sorry, Baidu doesn't care. Unless you contact Baidu and prove that there is infringement, Baidu may help you delete the post. No one knows when such a post will appear again. Therefore, I suggest that the landlord pretend to be a customer first, contact the opposite business, get the opposite company information, collect evidence, solve it through legal channels, and sue in the industrial and commercial bureau. Generally, it will be very intimidating and the problem can be solved thoroughly. With such proof, you will almost delete false information when you complain in Baidu.
