This question already has an answer here:
I posted an answer to a question here. Kendo UI Template: Invalid Template Error. A moderator deleted my post, saying that I was "promoting my site" and they don't allow external links. a) I see external links to blog posts that answer a question in more detail ALL THE TIME. b) I don't own github, and linking to a Gist that solves the problem is not self-promotion in any way.
The post contents:
For those of you on this thread, I've [posted a solution to this problem here]. Please let me know if you have any questions.
There were 15 different forum posts across different sites that complained about this problem, plus I ran into the problem myself. So I solved it, posted the code in a way that makes it easy to incorporate into a project with the offending project, and then linked to it from all of those different forum posts. How is that "self-promotion", and what I wrong with that? NONE of the other posts have ever been moderated that way.
Please un-delete my post. It is a valid answer to a long-standing problem many have seen on the internet. If you want me to elaborate in my post, then fine. But deleting it without asking me to change it first is kinda BS, especially when it is an accurate solution to the problem.
