the dev claimed they created an account (currently on BN rank) but they can't create ANN, and someone had to give his old account to the team so they can publish the ANN using said acc.
New accounts are limited from posting embedded images and have to wait for a much longer cool down time between posts, but they can start their posting with a thread.
The proper solution for the dev would be to buy Copper Membership. That allows a new user to embed images.
How about limiting the number of accounts that are created every day or lets say each hour?

It won't stop the spamming but it will slow down the process.
That would mean new (real) users have to compete with automated spam bots or click farms to create their account. It's worse than Newbie jail, so it won't happen.
