If you're not blacklisted, then you're fine, but it's a good idea to add a reply to your post clarifying what the issue is (seems like a newbie oversight?) so people know you've resolved it with Hivewatchers.

For communities, you can take a look at this post, but I'd really suggest not to cross post too much as it doesn't look nice for your readers. See below

And finally, hopefully you'll consider doing a self introduction post 🙂
