You should optimize your site so it loads faster and have a better colors for your site and add slider of images to make it better on the home page
Its clean and professional website colors are good but loading speed is slow according to me and you should have better logo for your site
It looks like someone is trying to hack into your account with hundreds of submissions. You might want to look into that!!!
According to me your site is looking good i really appreciate your work nice arrangement of the categories and nice layout keep it up good work
that's not really spamming this person just wants to submit his website to every single country If he submits a website many times to the same country within a 7-day period then yes that would be spamming
