5yrs is a very big number of years. When the account was banned back in 2018, didn't you create a ban appeal then? If you created, won't it be nice you bump the topic so that the moderators would have points to base their judgement.
You would not be unbanned based how long you have been banned or based on sympathy.
You must be able to convince the moderators by compelling how you have helped the forum in the pass.
I saw you offered services, how diligent were you.
For the sake of your services can you accept signature ban only?
I wish you good luck
