See the answer from "damoncloudflare" on this question. Given the user's activity across several of the SE sites, it's pretty likely he's a Cloudflare employee answering relevant questions he runs across. That's fine, obviously.
But there's no clear in-context disclosure statement, just the likelihood we'd infer the association by the answer being marked as from "[something]cloudflare." (Sometimes he refers to "we," but that's about it.) This seems clear, at the moment, but it's not durable. Keep in mind that:
- Users can edit their display name whenever they want. So if Damon later decides he wants to be TrollHunter269, his answers are suddenly all lacking disclosure.
- There aren't any restrictions(that I'm aware of) on display names, ie. does Googletorp represent Google? That's a pretty bad example, but the only one I could find quickly. I know I've seen people just type in the name of some service on occasion.
