Our latest story (also my first Mastodon post!):

Twitter users were drowned with adult content spam when they searched for information about the historic anti-lockdown protests in China.

Through data analysis and interviews with people behind bots, we found that much of the spam is linked to commercial bot networks.

How Twitter Bots Drowned Out Posts About Protests in China

Chinese protesters shared videos and photos to Twitter. But their posts were swarmed by escort and gambling ads.

We searched on Twitter for 16 cities and reviewed the results for spam. When we did the searches in simplified Chinese, bots were active throughout, for Chinese cities with or without protests as well as for foreign cities.

When searching the city names in English, the results returned no spam among top tweets.

The comparison underscores the inefficacy of Twitter and other large American social media platforms’ content moderation work on non-English posts.

The findings match a report published today by @det from Stanford Internet Observatory who reviewed millions of tweets by searching for 30 Chinese cities and found that bots were active before the protests began and continued after they had ebbed.

Content Moderation Survivor Bias

I talked to people behind two escort services’ spam accounts, both said that they provide escorts and use ad services on Twitter. One said they have no connection with the Chinese government, and said they also promote their services on Facebook and Instagram.

I also contacted an ad service seen in two spam posts and received a rate sheet. This business charges about $1,400 a month for an ad campaign on Twitter involving 200 bot accounts that will tweet at least 150 times a day.

Rate sheet:

Some analyses done around the end of Nov into this Chinese-language bot activity observed a “surge” from around the time when protests started, which invited the theory that it might be a deliberate information campaign.

@det explained this recency bias. "In retrospective research, historical Twitter data generally becomes 'cleaner' — some amount of spam and inauthentic behavior will have been removed...inauthentic content tends to appear most prevalent in the immediate past."

@det and us both did two queries. Mr. Thiel did one on Nov. 29 and one on Dec. 4. We did it on Dec. 2 and Dec. 6. We all observed a “surge” in the days immediately prior to every execution of the search query, “illustrating the unmoderated content bias.”

We found no evidence backing the idea that the ad campaigns are carried out by the Chinese government.

The ad campaigns do share some resemblance with govt operations, which is using swarms of bots to overwhelm authentic posts in search results. But those Chinese government campaigns typically use political hashtags and echo state-backed messages, unlike what we are seeing here.

Adding another layer of nuance:

According to one former Twitter employee who has analyzed state-backed influence operations, spam accounts can also be purchased and repurposed by governments from bot marketplaces, sometimes making it hard to tell whether a campaign is commercial or political.

@muyixiao On Alex Stamos's podcast they made the point that Twitter no longer has the people to stay up on foreign language keywords and block spam... so any popular hashtag will accumulate spam? Hard to say... race to the bottom.
@muyixiao If large numbers who were on twitter move to mastodon, won't the people behind the fake accounts try to follow us here?
