This is called a 'bounty' and can be applied on questions 48 hours after being asked, lasting for 7 days plus a grace period of 24 hours. The minimum bounty is set at 50 reputation, except if the user has already answered the question or has offered a previous bounty on the question. Bounties cannot be cancelled, and reputation cannot be refunded from a bounty, even if the question did not receive an answer. Criticism Trustpilot's page on Stack Overflow, the largest Stack Exchange, shows an average rating of 2.2 stars out of 5, a "Poor" rating. Although 30% of reviewers gave the site a good score, 67% of 136 reviewers gave the site a bad review of 2 stars or fewer. The website was accused by many users of having aggressive moderation that tended to exclude newcomers with lesser programming knowledge. Technologies used Stack Exchange uses IIS, SQL Server, and the ASP.NET framework, all from a single code base for every Stack Exchange site (except Area 51, which runs off a fork of the Stack Overflow code base). Blogs formerly used WordPress, but they have been discontinued. The team also uses Redis, HAProxy and Elasticsearch. Stack Exchange tries to stay up to date with the newest technologies from Microsoft, usually using the latest releases of any given framework. The code is primarily written in C# ASP.NET MVC using the Razor View Engine. The preferred IDE is Visual Studio and the data layers uses Dapper for data access.
