I don't think so. Since she believes(or wants others to believe) that Venus is a psychopath/malicious, Margo would have written those notes differently. For example, "have a boyfriend of my choice" would have been worded as "get a visa by marrying" or something like that, it wouldn't seem so innocent or like anything a normal person would want.
Seems like Venus wrotes these before she left for Manaki. As of now, Venus appears to have achieved a lot of the goals she wrote here(eg. getting her own life), and that's good. I don't really see much wrong with the notes Margo posted, other than the worrying weight goal (43 kg = 95 lb, almost certainly underweight for her). However, I still don't think that's adequate evidence to back up the claims Margo made in the caption. I also think she could have done better than posting Venus's private stuff.
*facepalm* I myself thought it was a real cat at first until other people said it was edited. Maybe she put the cat gif in there as a cool special effect, but considering how many people are convinced, she probably meant it to make others think she actually has a cat, aka. the omni-talented kawaii Chinese princess who's also living the cool life with a cute kitty. (No cat emojis available?! whaaaaaaaaaat?!!)
hmm...haven't thought of that! Considering it was an English post that was quickly deleted, few, if any, Japanese people would have read it, let alone anyone who knew Manaki irl. Maybe Manaki himself didn't even see it, so Venus would have to be careful about bringing it up anywhere if she didn't want to unnecessarily strain their relationship. There's also a chance that the news never reached Margaret, and Venus might just not care anymore about getting exposed by someone again.
she sometimes wears wigs like in this video, but she also has extensions, which you can see in the bed cafe video where her real hair length is visible on the extensions. I personally like the layered effect that gives her.
Her hair looks a bit more brown in this video. It might've looked full-on black in other videos because the filter she uses makes everything more bright and cool-toned, perhaps taking out the warm/yellowy tones the make her hair brown instead of black.
Even if Venus was trying to allude to Margo's animosity toward Manaki, she should still apologize. It's been over a year since she ran away and Margo tried to smear him. Besides, Margo's become quite irrelevant now, most people will not get the reference and misunderstand it as real or terrible taste. C'mon Venus...you've come a long way from your old snowflake days, we know you can do better than that. However, she does seem to have a tendency to hide mistakes instead of coming clean. For example, she never changed the titles of her "how to look half-Japanese/like a Korean girl" videos when people complained about it. Instead she made a video defending herself. I agreed with her defense in that particular case, but she sometimes comes off as defensive(?) if that makes sense.
I speculate that was because Venus was no longer useful to her when she ran away. There are screenshots in this thread from before the drama that shows Margo kissing up to Venus in her social media. She reminded others that she was Venus's mother whenever she can to share in on Venus's popularity, and keep the youtube $ flowing. After Venus left, Margo could no longer use her for profit, she had no reason to not spread rumors about her daughter as revenge.
