By using the Twitter \ac{API}, Hybrid \ac{OSN} is very strongly bound to Twitter. Restrictions to the \ac{API} would have a significant impact on the Hybrid \ac{OSN} client. In order to link content and actions to users and tweets, a referencing of the respective id is necessary. If these ids disappear from the system because tweets are deleted or users leave the platform, the private data can no longer be assigned and lose their significance.

-Private tweets are loaded into the user's timeline by active pulling. With the user ids of the friends' accounts, their private tweets are looked up. Since the data structure in GUN is optimized for searching by user ids, searching for a keyword or hashtag is not possible in an elegant way. To perform such a search, first, all hashes need to be extracted from GUN and downloaded form IPFS. Second, all this data needs to be decrypted and searched locally for the given keyword. For a small amount of data, this is maybe practical. However, it does not scale and is, therefore, no permanent option.

For the hybrid client to achieve the best possible result, a copy of all the functionalities of the original \ac{OSN} must be implemented decentrally. In particular, the problem of finding specific content has to be solved. GUN fulfills this requirement only partly since only user ids can be looked up. Besides, GUN needs a relay server to connect peers. This server represents an unwanted single point of failure.
