Why would you use a throwaway email address? Don't you know that whoever is running the throwaway email server can get all the messages that the forum sends you?
Apart from that, but anonymous email signup services like simplelogin and passmail (proton pass) completely cover all the benefits of these throwaway email addresses, minus the risk of losing access to email reset.
If I am to be any true to myself, I didn’t dig deep on the what risk I stand to incur by using a throwaway email address and that’s entirely my fault, I am owing that. It wasn’t the original plan and it only became an option after I had tried using my functional email to create an account and the evil IP thing came up. My next trier failed to accept previous email as it had been used and so, the throwaway email became an option. I felt I could change it as time goes and that turned into procrastination coupled with the fact that, I was still getting used to the forum.
It only dawned on me after the incident of a forgotten password and good enough, it wasn’t too late to think and rethink to come up with the combination and make necessary adjustments.
