Everliker extension is no longer available on Chrome WebStore following a spike in Action Blocks end of June 2019.
You can still get it as a Standalone Package here but please take your own judgment as you are using it on your own risk:
2. Navigate to "chrome://extensions" url in Chrome, enable Developer Mode in the top right corner.
3. Click "Load Unpacked", and point to the unzipped folder.
Action Blocks are failed like attempts. If Account / Device / IP combination is like blocked, liking a post from the browser does not register the like on Instagram server. Refreshing the post page after it was liked returns a page with an empty heart, i.e. not liked. Everliker detects such failed attempts and shows the Failed to Like! message, stopping all tasks automatically.
This problem was first detected by services automating follow / un-follow end of May 2019. It appears to be common and all services are affected.
Our tests, data collection and engine updates show that Instagram has changed formula for account trust quota. The action blocks are not (as far as we can see) caused by Everliker but by breaching the trust score limit.
Instagram uses a trust quota approach to prevent like and follow functions abuse. Each action taken on an Account / Device / IP causes that Account / Device / IP trust score to change. Liking and following depletes the trust, while posting improves it.
Fresh accounts and Devices have low trust scores. As the score reaches 0, certain actions are blocked automatically. Trust score is restored over time.
Liking above 100 posts / hour was possible before, now it quickly gets devices (Chrome sessions) action blocked. The highest setting that works on test accounts is 30 likes / hour or 600 likes / day. Other speed settings are being tested to pinpoint the consistent speed limit.
A better speed control module (under General Settings page) and IP leak prevention system were added to Everliker. We are still looking into the issue in hope to find a solution.
