So I have checked both solutions here mentioned for the comments.
[TH] solution has so many bugs, errors that it's actually not ready for production, yet.
[tl] has a nice design but many useful features from the stock version has been stripped, plus several bugs.
I contacted both of them to fix the issues, but i think they will not even bother.
Therefore I guess the only solution is to hire someone to create a proper comments system. If you know about anyone willing to work on it, please let me know.
