If you have limited time in the evenings, use a recent photo with your face clear — that is the part that actually moves the needle.

When you are after something serious, the niche ones tend to feel a great deal worse than they are, and it makes a real difference. Speaking personally, the read receipt setting is the thing that decides it, even if sites that skip verification rarely say so.
