Besides which, the terms of ClixSense don't allow changing of uplines. People need to learn to read the terms of each site they join, so they won't be surprised.
About: User Agreement - ClixSense
Quote:Sponsor Changes - The changing of or removing an affiliate sponsor is not permitted. The management of ClixSense may at its discretion allow the changing of a sponsor, IF and only if the affiliate does not have a sponsor assigned or the current sponsor has been inactive for more than 90 days. There are no exceptions to this rule.
It's also not fair to the person you joined under, after they've promoted (most probably through buying ads).
These people who tell you to change your sponsor are totally dishonest and are leeches looking to score quick referrals without having to work for them like the rest of us.
This practice makes my teeth grind.
