I scrape then use GSA platform identifier which works well sorts and filters out dead links before you import in the software
Program runs fast when sorting out links like 10 X faster then GSA SER.
Loopline is good you don't need re-captacha's when using the identified or verified lists (I use only on profiles) only the text and re-captacha which cuts a huge costs. I barely use the text and re-captacha list because the best list are the identified or verified. LPM are over 500 mostly contextual a lot of wikis which you don't find a lot in lists
Plus they are updated 24/7
I use solid proxies they are automated proxies if they dies or get banned they get replaced instantly in SER while it's running so you never have to stop using SER. I use their dedicated server as well
