Hello everyone!
I'm posting this one really just for a data point for others, since Capital One tends to be all-over-the-place recently with CLIs (even more so than usual).
My old QS MasterCard, opened in June 2007 as an Orchard Bank (HSBC) Platinum with a $300 credit line had been consistently getting CLIs the last few years - the last was $1k October 2016 - but back in the spring when my six months were up it was a no-go... I got the dreaded "not enough use" default message that so many here have come to know and love. 
I only used it sparingly (since I have other cards with both higher limits and better rewards) but I figured I would see if working it relatively hard for a little while would make a difference. In September I put just under $2k in purchases through it, and even then when I tried for a CLI I got the same "not enough use" message. I tried a couple of times last month as well with the same results. I figured I would just forget about it since with this particular card it's not really a big deal anyway.
I noticed today that the Capital One site has had a make-over, so I figured 'what the heck' and gave it another go... this time I was successful:
I doubt the site makeover had anything to do with it, but I'm pleased that after all this time I've finally broke through the $5k barrier with this card. 
It has a legacy 15.9% APR, which is actually lower than my other two Capital One cards (not that I would ever carry a balance on it anyway, of course) and due to the age I don't plan to cut it loose anytime soon (if ever).
At some point I might play around with a PC; I would love for it to become a Savor (I would actually use it then), but from what I've read most PC requests for that have been denied. I might PC it to a Venture One to see if it would get the WMC upgrade but that would be purely for 'kicks' and for the data point, since I've not seen reports of a Platinum to WMC upgrade in a while.
TL;DR... if anybody has had a difficult time with Capital One CLIs lately don't give up! 
Update: I ended up getting a CLI on my Venture WEMC as well, and it's barely been touched since the spring (seriously... less than $100 in charges since March). You can jump directly to that post by clicking here.
Hey, job well done UncleB on keeping the flame burning. Congrats on making it 10 years with the card lol, something many of us should strive for , longevity lol. Maybe 1 day theyll let you pc to the hunger card . Enjoy and thanks for sharing

Congrats UncleB.. Funny you got one after the conversation we just had
Congratulations!
Congratz on cli!
I currently have a QS1 that hasnt received a cli. But earlier this year I closed a Cap1 Platinum. And for some reason even though it's closed I'm always getting a cli on that account (closed). I don't know if it's a glitch witb Capital One lol
Congrats on the CLI! You inspired me to try for my own CLI on my old QS.
Nice going! Closed all my Capital One, Orchard and HSBC's when the big 2009 take over took place by Cap1. Did not like that they were going to take the Business Cards to reporting on the credit reports. Also, credit limit increases by them for me got so it was always present CL not used enough. When I closed them there were eight accounts. Glad to see Cap1 is CLI'ing for legacy cards. Maybe it is your legacy Tell CC to "eat his heart out"
