Hehehe@desert that is my inbox.
Mine comes in waves, but I've not had any new ones lately.
For me, I put questions in my profile at various points. If they make an attempt at answering them, I make an attempt at replying.
I've seen other subs put colors in their profile, a different color to put in the header depending on how far down they have read.
ALWAYS, ALLLLLLWAYS read their profile first! If it's blank or limited, just ignore them. If they have a detailed profile but no blogs or forum posts, be wary. They may just be looking for some ass.
If they list blogs that they follow, look through them. You'll know what they are interested in. If those blogs are not recent, you know that they don't come here often so may be on the rebound. Use caution.
Check out WHEN they joined as well. If they are an old timer (2018 or older), and they don't have a blog, you know that they probably found someone and now it's over, HOWEVER, that doesn't mean they are on a rebound. They are USUALLY experienced enough to know better. I think the site started in 2016 and those members have a lifetime premium membership. Treat them with respect for being the founding fathers/mother's.
