Well, that would bring it down to 7.5 years.
I think the sweet spot is more like 2 years. Anyone helping out the community that much (keep in mind to reach VIP in 2 years, you'd have to create a new thread 5 times every day), is likely dedicated to helping the community. I was continuing to make posts and reply even when we didn't know of anything there was to work for.
I think Anker will step in if it is obvious a user is making multiple posts every day for the main purpose of getting to VIP status. That being said, that hasn't really been an issue so far and I see no reason as to why it would start now. Plus, lots of great those people may come from sources like social media. I don't think Anker is going to advertise the benefits of senior, executive, or VIP membership on social media. And, those people probably don't have the "time" or desire to dig into the site themselves and discover that info. And even if they did, I don't think many, if any, would post for 2-3 years knowing that chances are they will get caught by @AnkerOfficial, you or @TechnicallyWell and no longer have the ability to earn pts or something along those lines.
In other words, I don't foresee it as something we should be very concerned about.
I still think it would be easier (and not cause as many issues as advertised) to revert back to the previous pts system and just keep the level requirement.
Also consider that if we go the pts route some of us would have already earned pts from the previous system (just makes it more complex).
If after reading all this you still think it would be better to just change the pts required to get to VIP status, this is my suggestion. Remember, @AnkerOfficial thought it should take just over a year for @nigelhealy and I to become VIP members. That takes a lot of dedication, as it should. IMO it would be necessary to rework all the levels. That would also require starting over everyone's pts and possibly give them gifts based on how many they had.
Now, if you posted 5 threads per day, replied 5 times a day, liked 5 times a day, get replied to 5 times a day, and get liked 5 times a day, then it would take you 2.5 years to reach VIP status. So basically that would mean Anker is encouraging everyone to make at least 4,545 posts to get to VIP status if they want to get there in the shortest time possible. Do we really want that?
That's why I think it would be easier (for Anke and everyone) to just revert back to the old pts system.
