Help understand GSA SER

I'm such noobie when it comes to SEO and especially when it comes to GSA SER. I'm just wondering if you guys can help me understanding some of the basics when it comes to using GSA SER.

I'm wondering, what does it mean when it says "Project Stopped"? Like does that mean the campaign/project is permanently done or something? It says stopped, yet it still shows active. The weird thing is.. I only have 160 submitted and 180 verified links. Yet then there are Fiverr gigs where they make tens of thousands of links per day, or other people on this forum making 10,000+ backlinks per day.

I also don't really understand what all this verification error messages. Before the project stopped I must have had like 100 messages saying verification was not successful and I don't even know what that means. here is an example of what my log said.

[-] 100% Verification of General Blogs not successful - hxxp://xxxxx.com/xxxxxxxxx/
[ ] Verifying finished (161 checks done)
Project stopped!

What do you guys think?

well it means what it is, project stopped means project stopped, verification not successful is verification not successful, SER isnt a sphinx tat speak with riddle.. submitted links will go to verified when its verified so if u gt a good list its normal to see verified higher than submitted; fiverr guys use 1 AA list that they just use over and over again, the number of links u can generate a day mainly depend on ur list..
