I would not recommend doing this. It's a huge red flag for everybody in the community if you're looking to self censor people. The moderators do a good job of enforcing the rules, so simply report any posts you think are breaking them. Deleting comments yourself, or even giving yourself the ability to do that, is a BIG anti-crypto policy and so that will reflect poorly on your service/business. As for your ANN thread appearance, maybe hire somebody for $40 or less to make a graphic for you?
