Deleted Discord Data Concerns

Since both parties have deleted their accounts and there is no evidence, it's unlikely that a report would lead to legal consequences. However, it's always good to be cautious.
Are you currently worried about any specific legal action being taken against you?

Based on what you've shared, it seems unlikely that any legal action could be taken since there's no identifiable information or evidence. However, it's always wise to stay cautious.
Is there any particular reason you're worried about this conversation now?

Law enforcement can request data from Discord if there's a valid legal reason, such as a court order or subpoena. However, since both accounts and conversations were deleted, it may be difficult for them to recover any meaningful data.
Are you currently involved in any legal investigation or received any notice from law enforcement?

Since you are not involved in any legal investigation or have received any notice from law enforcement, it's unlikely that there will be any issues. However, if you remain concerned, consulting a lawyer can provide you with peace of mind. Do you have any other legal questions or need information on a different matter?

Since your account has been deleted for almost two years and you've not heard anything from Discord or law enforcement, it seems unlikely that there will be any issues. Law enforcement would need a valid legal reason to request data, and deleted accounts make it difficult to recover information.
Do you have any other concerns or legal questions you'd like to address?
