I have used AdPlexity for many years as well as Social Ad Scout. I have tested most of the others in our resources area and found most all of them to be very easy to use and very similar in their results.
There is a new spy tool that I have tested and its name is AdFlex. It is free and has an accurate and large database of ads, especially crypto-related ones. BigSpy is one of the big names that I have used recently and they also provide great in-depth data on ads.
Attention: "role based name" email prefixes such as support, webmaster, info, contact, forum, service, affiliate, admin, traffic, partners, marketing, etc., for our member accounts are not permitted. They are acceptable for a vendor listing, but not for the member email. This is due to bulk email processors scrubbing them for delivery due to extremely high bounce rates. Please apply for membership using a personalized email prefix. Something like email@example.com.
If we discover you signed up with a role based name we will give you only one message to change it. After 3 days your account will be removed if the email is not changed.
