Since there wasn’t anything broken on our end, there shouldn’t be anyone else impacted by this. But as part of making sure that OP wasn’t visible by mistake, I had my team double-checked to make sure our previous fix from last year was properly retroactive. It was.
More generally, I don't think that tricking anyone is a viable way for us to run a business. We’re trying to create a marketplace that can open opportunities for engineers who wouldn’t otherwise have them, and we need the trust of engineers in order to do that.
But if I had to guess? It's because we've been ramping up a feature that is increasing the amount of outbound on our site by a very large margin (currently almost an order of magnitude) from where it was a couple of months ago.
