I will never remove your post from the site, the dofollow links will be there forever.
Any number of links within the blog post is permitted but I would strongly recommend only using 2 at the most, Google seems to prefer this based on my experience.
Current topics are: Travel, Tourism, Car Rents, Flights, Business, etc..
1. Your article must be of 400+ words
2. Article can contain no more than 2 links (dofollow)
3. Content must be unique/original
4. Duplicate or spun content will not be accepted
5. Articles not related to Casino/Gambling will not be accepted
6. You can send me 2 relevant HQ images of your choice
7. Or You can give me your site and anchor text if you want Backlink in sidebar
I will also include a relevant photo/image from the Flickr Creative Commons to give your guest post a very professional look.
