As noted no your screengrab, you responded to 7 out of 8 invitations to apply in the past 90 days. I've checked your My Stat page and can see that the number of invitations to apply on your account has increased.
One of the best ways you can demonstrate your professionalism to your clients and potential clients is to reply quickly to job invitations. Replying doesn't necessarily mean accepting. Declining jobs you don't want and informing us about spam are equally important. You can set your profile to private if you are busy, on vacation, or cannot reply to invitations for any other reason.
