Gosh anyone that uses a free thing such as .blogspot.com is probably legit but just avoid them due to them not investing even a couple bucks into buying a domain. The faucet / micro-earnings sites are already over-saturated and you could easily find a much more exciting site that you know is reputable and pays out.
I guess this thread belongs to micro earnings as what you are mentioning the above sites are all about faucets. You can move this thread OP by clicking the 'move topic' in lower left part of the thread, and move to Service Announcements > Micro Earnings. Or some mods can move this.
Regards.
If the mods feel as if it should be moved, they'll move it so you don't have to worry about OP here.
