    1. If you are planning on hijacking one of their online accounts, then obtaining all possible intel about someone helps to make phishing their other service providers easier. Knowing someone’s IP address means you instantly know what city they are in and who their service provider is.

    2. If you are trying to reveal someone’s true identity and you have already learned of their IP address through some other means, then this would allow you to reveal their identity on lemmy. Example: an employer already knows the home ip addresses of their employees who work remotely and vpn into the company office. They see someone on lemmy sharing insider info about the company they would rather not have shared and suspect the lemmy user is a disgruntled employee and send them a dm with tracking pixel to verify whether that lemmy user’s ip address matches the addresses of any of their employees.

    3. Consider the case of someone thinking they are anonymous and boasting about some activities that might be legally questionable, then consider some law enforcement agency using tracking pixel to get user’s ip address. If the lemmy server is outside of jurisdiction they might not be able to subponea the lemmy instance admins for that user’s ip address, but now they don’t have to. With the IP address they can just subponea the isp to get the user’s identity. This could be over criminal activity…or maybe just something like admitting being gay in a country that sentences to death for that.

    These are just three examples…there are countless other examples just as bad.

    TL/DR: it is a significant security breach to allow 3rd parties the ability to use the platform to expose user’s ip addresses, and even worse when it can be targeted at specific users (such as the DM scenerio that is also affected).
