Your original post was well written, so a mature discussion deserves a proper response. I'll try to highlight specifics so you can get some direct answers.
This has two parts, getting a script approved and getting a git account set up.
First, I have never made a git account for anyone here since I joined 3 years ago.
Second, there are a lot of reasons why a script may take a while to be approved. Now the phrase "a while" is pretty subjective, most people who I see that are unsatisfied have waited well under a week. One week turnarounds are pretty standard after the script is completely finished. If a scripter claims that a script is complete and I find numerous problems with the code, the scripter is then directed to fix the issues prior to release. This is the main cause for scripts being delayed, so please ensure your scripts are actually ready before they get reviewed.
This is not quite how the process works. There are two different tracks, one for free and one for premium. Premium scripts require a plan review prior to developing the script whereas free scripts require no such plan, and you can release after it's finished. Many free scripts are made by newer scripters/programmers and are often bug-prone. I spend A LOT of my time coaching people on proper techniques. Once again, delays are caused from the issues highlighted above.
The SDN is not guaranteed. Only properly written scripts will have the opportunity to be distributed to thousands of botters. It is a direct reflection of our services.
This community has also been plagued by people who have distributed malicious code and people who have attempted to distribute malicious code through the SDN. Unlike other communities who risk their user base by not performing reviews, we spend a lot of time sitting down and reading other people's code rather than writing our own.
