\begin{itemize}
|
|
|
\item \textbf{Minimal additional effort}: Installation, configuration, and operation should be as simple as possible. Increased complexity is an additional barrier to the acceptance of the solution. All users of the \ac{OSN}, especially technically inexperienced users, should be able to use the hybrid solution. For the success of the hybrid solution, wide distribution is essential, so no user groups should be excluded.
|
|
|
\item \textbf{Minimal side effects}: There should be no limitations for regular users who do not use the hybrid solution. Cryptic messages, disturbing content and other disturbing elements should be avoided. Annoying messages could lead to the user being blocked by other users or cutting off contact with them.

- \item \textbf{Compliance with policies}: By registering, the user agrees to the terms of service/use. It is important not to violate these conditions; otherwise, the user would have to bear the consequences. The severity of the consequences depends on the respective terms of use and the type of violation. For the hybrid solution, it is therefore essential to adhere to the \ac{OSN} terms of use as well. Otherwise, legal use is not possible.

+ The Twitter Terms and Conditions allow the crawling of content within the rules set in the robots.txt file \cite{twitterXXXXtos}. Facebook completely prohibits the use of automated methods, thus excluding the possibility of crawling \cite{facebookXXXXtos}. Compliance with the guidelines therefore also directly restricts the possibilities of technical implementation.

\item \textbf{Good user experience}: The user should be offered the best possible user experience to increase the acceptance for the solution. A bad user experience causes frustration and will in the long run not lead to success of the hybrid solution. Good user experience includes:

|
|
\begin{itemize}
|
|
|
\item Short loading times, so waiting times are kept to a minimum. Hence, finding and loading data hast to be quickly.
|
|
|
\item The user interface of the hybrid solution should be simple and understandable and have a modern and appealing design.
|
|
|
\item When integrating into the \ac{OSN} user interface, the existing layout should not be broken, and additional control elements should be inserted in the same design.
|
|
|
+ \item Privacy should be protected by design. The opposite is known as dark design pattern \enquote{Privacy Zuckering} (named after Facebook CEO Mark Zuckerberg), when controlling the privacy is purposely made difficult \cite{facebookXXXXzuckering}.
