It is a community and for a onetime upfront fee, the community will give you a lifetime of support as long as you maintain the quality standards.
This comes in the form of an automated airdrop every 24 hours by their Qurator bot.
The current automated system not only checks all members, but checks on activity. As soon as you post it is notified, if you comment it is notified. It then comes by provides some support.
The only requirement is that you have a new post to vote to vote on. Only posts after the previously voted post is considered. Let's look at some examples,
There are some requirements, such as tags that are not supported by the project, but the details on this can normally be found on their daily or sometimes weekly update.
It is also possible to get an upvote even with everything in order.
The bot like any other is subject to errors. Every qurite that posts to steemit gets checked twice, and while the error probability in this case is small, it still exists.
It could happen that you are being checked at a time the site is extremely busy leading to timeouts - i.e. check failures.
In case this happens there is an additional service where every member is checked by the bot until all members have been checked.
Activity (qurites that post) is prioritised and the loop through all members is secondary. So people that are active get checked first and when activity dies down the bot uses this downtime to continue its checks. This means a complete check varies, but as of current it takes 5 - 6 hours to check 1000 members.
