There are many people with great ideas, we all have them but the company will only implement what they wish depending on the direction the company wants to take with the software, if making a change to notify someone is not required then why waste time? If the system has worked fine for years with only a handful of threads similar to this one asking why or why not something is done then its fine and does not need updating.
You're not wasting time giving out solutions, you truly didn't give any... not saying that smart but the system/setup is fine as-is, these ideas of yours are just that, ideas and while you deem them worthy enough to warrant change, that is your justification as to why its required not the companies. Genuine customers are the type of people who would never download and install illegal/nulled software to begin with - they would genuinely pay for it, genuinely test out mods, and genuinely enjoy the support provided on vbulletin.com and here on .org that they genuinely paid to access. Did I say Genuinely? Genuinely pay for something and you can genuinely enjoy it without shame!
