Yes even it's no follow it still passes the buffer and pass the signal. I am having great success with Pinterest , reddit, fb such pages as buffer and gsa blasts. I believe the quality depend on how normal the backlinks. Don't try to over optimize with keyword anchortext. Consider on brandable anchortext and you can easily balance anchor text ratio with gsa.
Actually I disagree. I build nice stable links with gsa. It all depends what engines you going to use. Article platforms , forum platforms getting decent self hosted pages with low obl values. Don't use default gsa tokens instead try to customize with gpts
