Anonymity can avoid being targeted by management. The manager may reveal complainant.
True. If you complain directly to management, management will know who you are. And the more complaints of a
minor nature that you make could result in the termination of or non-renewal of your lease.
An anonymous blog that lists your complaints about the living conditions at the rental could be one way to avoid confrontation with management - but it does little to resolve the issues you have with the way management manages the rental. And it puts you at risk of a defamation lawsuit if you are not careful what you write.
In your case, I imagine you would not be all that “anonymous” on your blog because you seem to have a unique set of complaints that others residing at the complex are unlikely to share.
