I never buy done for you websites and would recommend anyone to buy, especially in the IM niche. The reason they are done for you is because they benefit the creator of that website in some way, but not you.
They either have links that go the another website of theirs, or pays their affiliate commission and not yours, or builds their list and not yours, or has their ads on it and not yours, or brands them and not you, etc., etc.
It's always something that benefits those selling or giving away the Done For You websites, but never benefits the buyer of those sites.
