It is common knowledge that the plagarism checker on Codeforces is not perfect, as it sometimes gives out false positives. I happen to be one of the few victims of such falsely given flags.
About 6 months ago, I received a message from Codeforces saying that my submission to this problem is too similar to somebody else's submission, and all of my submissions for that contest got skipped. For context, I solved 2 problems (A and B) in that division and got negative delta (-23 points), so I actually gained rating after that contest was purged from my profile.
I tried writing an appeal here, but I never got a proper response from anyone. To this day, my profile displays a history of one skipped contest, because of the false plagarism flag.
On some contest announcements, I see people calling out the problemsetter for being a cheater, because he/she has a history of some skipped contests. It seems like to the general audience, having skipped contests is equivalent to being a cheater. I hate the fact that this false plagarism flag has the potential to ruin my profile and label me as a cheater, when I am a legitimate player.
I want to know if there is any way I can appeal for this matter. I do not want a false plagarism flag ruining my profile.

Nope. Only blog 8790 and it is flooded with malicious appeals written by cheaters using "evidence" like "bhai i used ideone" so chance of your appeal getting viewed is small.
Also, your comment does not contain concrete evidence (of which as the blog states, the only valid type is material published online with a timestamp, which obviously does not fit your case), so CF admins will likely just skip it even if they read it.
However, since this is a matter 6 months ago and you continued to participate contests normally, I think it doesn't matter that much. I believe no one will call you out here unless you have >1 skipped contest (which means you are truly a cheater) or you act like s**t in comment section after getting caught. Have a good day!
Thanks for your comment.
I am quite concerned about this thing happening again in the future. I don't want my honest efforts be ruined like this.
