First:
The flagging was done by a forum member not Jolla.
And open repos link are fully allowed.
Second:
So I had that happen to me (mainly based on misunderstandings or even wrong assumptions 
clarified via PMs 
).
And also seen a few other occurrences.
Really problematic is you have no idea who flagged you and have no chance to ask this one personally why he did that. (in earlier times one could guess based on badge timing 
)
I do not see any problematic wording in your posts but as said flagging can be done by anybody who might feel different about it.
It is up to you to edit that post and it will reappear. No idea how the guy will handle that: it might re-flag it and it will be hidden for good or it might let it go.
TBH this is something I do not like with this forum SW. At least one should get notified who flagged own posts or this should be only done by forum admins / high-level members…
(reasoning for flagging to suppress spam is another topic)
