Today, the story is different. Domain name registrars realized that they could auction expired domain names to the highest bidder and generate additional revenue. If no one wanted the domain names in an auction, the domains would then drop and become available for anyone to register. Much of the time, however, domain names are successfully auctioned.
Once a domain expires, the registrar will allow around 30 days for the original owner to renew it. This period depends on the registrar and can range from 2 weeks to a whole year. Once this period is over, the domain enters the "Pending Delete" status, during which it cannot be renewed, purchased or modified in any way. Once the Pending delete status is over, the domain is dropped back into the available pool, and can now be purchased by anyone.
Let’s just say for example we wanted this site, It looked good based on our analysis and we’d head over to Snap Names, Nameja is another one and what these service do is they have special technology on their site that allows them to try  to register a domain on your behalf over and over again. Okay? If you tried to do that your IP would get banned, but they have some system where they know how to do it just enough to get the domain, but not enough to get blacklisted.
Hey, what’s up everybody. It’s Brian Dean from Quick Sprout. In this video, I’m going to show you how to buy affordable expired domains and how to evaluate the potential value that an expired domain could bring to your site. Now, expired domains is pretty gray hat, black hat type of thing because there’s basically two things you’re going to do in an expired domain.
Here's an old post on search engine roundtable that claims google's policy is to discount previous backlink juice when a domain changes ownership.  I'm not convinced whether this is actually true or something Google says to discourage excessive domain buying / 301 redirecting for SEO benefit.  The comments above seem to give varying opinions on this matter. Would be great to get to the bottom of that one!

Answer: Registrars are not set-up to negotiate the selling price of expiring domain names. Their technical support team likely won’t even know what you’re referring to, let alone who to refer your inquiry to. It’s likely your offer won’t even be worth their time to handle. Unless you know the founder, president or chief operating officer of the registrar, you won’t even be able to have a dialogue about it. In addition, depending on how they interpret the ICANN registrar rules, it may not even be possible.
I’m ready to purchase domain hunter gatherer after seeing your video but I’m a little scared to spend money because all I need is information for South Africa and the Domains that expire for if you can do a quick check (not a long as the video ) on the features it has for and let me know id show my appreciation by purchasing immediately as this is my only concern.
So, let's start off with the simple website list crawl. So settings for this is covered by the general crawl settings and these apply to all the other types of crawl as well, such as the Search crawl and the Endless cruel, so pretty simple really. Delay between each request to a website. One second, this is in seconds. Secondly, concurrent websites crawl how many websites you want to crawl at any one point in time and then how many threads will concurrently crawl per website. So that's ten, a crawl of ten websites at once, and each of those websites there's three different threads crawling. That's 30 concurrent connections you've got going.
The whitelist filter for wanted characters is now split into three filters. The old whitelist is now named whitelist (only). When used, the domain has to consist only of the defined characters or numbers. No other characters are allowed. The new whitelist (any) filter finds domains that have at least one of the defined characters or numbers. The new whitelist (all) filter finds domains that have all defined characters or numbers at least once.
