How can I whitelist my bot? [Appeal]

Due to a misinterpretation of the current DM limits and because there was a server blackout, my bot ended up sending DMs to notify users they got kicked out of a channel. My bot was flagged for this reason and although we removed all unsolicited DMs and submitted two appeals, we have not received any response yet and it has been more than 2 months now. 

Is there anything else that I could do apart from submitting an appeal to get my bot whitelisted?
