Hi there, doing adwords + affiliate for long time with good results, but these days, google ban my account's with no reansons - payment's ok, cloaking off, longtime good loking account's just banned.
I believe it is because affiliate links on my landingpages ( bridgepages ).
So now, i had few ideas, how to avoid it.
1. Email form
I will remove button's and affiliate link's from my landing, and replace it with short form ( name + email, or just email ). If visitor put his email there, he will be redirected to thank you page, where will be redirect to affiliate landinpage ( affil link ).
Bot's wont see this, and when manual reviewer come to my website, i hope he will not fill the form.
The bad thing on this idea is so small % of traffic want put her email's somewhere.
2. Survey
I will do small survey instead of affiliate link's on lp. Like 4-5 steps. When someone going trought all question's, he will see button with affiliate link.
Bot's and manual reviewer won't see this ( i hope ), and there will be much more % of people who fill this ( compare to email form, i think )
What you guys think about that methods? Will share some experience with someone who sucessful running adw+affil.
Thank you
In general it's better not to underestimate Google machines, at the end - we never know what exactly they will ban and what not and how their system works. Be careful, because if you get blocked again - you might be banned forever.
As in regard to your 2 options, the second one looks more convenient.
I agreed, think that Survey is better 
I have tested alot and find out that for me it's my Affiliate Keyword which is getting account review in 2 hour and account banned after 1 day..
Also as per my recent experience be careful with your negative keywords. Avoid keywords like : scam, reviews etc. as negative keywords. This will definately help
