JAVEE, VPN's & BUYING AGED FB ACCOUNTS

I have used FB to advertise various products/servicee for a few years but always done it manually,posting ad's to about 200 groups, and regularly bumping them to to the top with comments. This was initially done on 8 year+ accounts (our own personal accounts with genuine profiles, friends etc). I often would get temporary blocks for bumping to fast or joining too many groups at once (more so recently) until both our facebook accounts were permanently disabled for copyright infringement (the Premier League reported numerous IPTV ads we had posted on loads of sites) so the accounts were lost. Creating new accounts hasn't worked as they soon get blocked.

I've been researching Javee and it looks as though it would be a great automated solution for marketing our services/products, but would like some advice on how I should set this up. If I buy aged FB accounts to post and comment in groups (post ad's then bump them) is there a certain age of account I should invest in. For eg would a 3-4 year account have more chance of being blocked than a 5-7 year old account or even older. Am also right in thinking, I should only consider phone and id verified accounts for this purpose? Also, I am located in Spain, will I need to use a VPN for this and if so, could anybody give me any recommendations? Also, are there any guidelines to how much you should limit each account to post or what you should post in addition to the adverts to make the account look "normal"?

Sorry for all the questions, I'm really looking to learn as much as possible about social media marketing and am happy to do lots of reading, I could just do with some advice and for somebody to point me in the right direction.

1) you should use private proxies instead of vpn, it's cheaper and good. 1proxy = 1 acc
clean cookies and all web data everytime you switch acc. You can use the chrome extension "Click&clean"
I suggest highproxies but there are a lot of good providers (maybe cheaper)
2) yes age matters: 3-4 years acc is good but 5-6 years is stronger. Anyway I think 3-4 years is enough cause they are cheaper and strong enough if you don't spam too much
3) You should buy aged accs with pic verification passed or you can use photos taken from vk to try to pass this kind of verification. Don't use google or instagram photos or you won't pass it.
4) use getsmscode to verify with phone or buy PVA, after verifying remove the number so that if you get any verification again it will be the phone verification 99% and you can verify again
5) don't spam too much, you need to look like a legit account. Do other actions (like, share, comment)
6) enter not more than 10-20 groups per day and spread them over the day. fewer groups per day = safer

Many thanks for taking the time to reply. That's cleared a lot of things up for me. Can you recommend any of the FB account sellers?
