Spam and deepfake nudes
In which a swarm of X accounts floods the platform with spammy posts promoting an AI nudifier app
One of the more unpleasant consequences of generative AI technology has been the emergence of AI “nudifier” apps; in other words, software that takes a photo or video of a person as input, and generates a version of the same photo or video with the person’s clothing removed (often without that person’s awareness or consent). Posts advertising these products have proliferated on a variety of social media platforms of late, as reported by Alexios Mantzarlis at Indicator.media. In some cases, this advertising is heavily astroturfed and makes extensive use of inauthentic accounts (perhaps due to a lack of real users willing to admit to using software of this sort). Here’s a look at a network of spam accounts on X promoting the Undress App AI “nudifier” software.
Recent X posts containing links to Undress App were harvested on three separate dates, June 1st, June 9th, and June 10th, 2025, and post histories for the accounts involved were gathered using a combination of Wayback Machine and Nitter. After removing false positives, this yielded 954 accounts; the true size of the network is likely larger due to limitations in the aforementioned data acquisition methods. These accounts are a mix of newer accounts created within the last three months for the purpose of posting spam, and older accounts that appear to be hijacked due to lengthy gaps in activity prior to the spam posts. Most of the accounts have very few posts; 782 of 954 (82.0%) have ten or fewer posts, and 389 (40.8%) have only a single post online at the present time.
Thus far, the spam accounts have posted at least 2626 similarly-worded X posts promoting Undress App. On any given day, only a subset of the accounts activate; just 15 accounts participated in both the May 31st spike and the June 9th/10th spike seen in the above graph. In some cases, the accounts delete the spam posts 24-72 hours after posting them, although many of the posts remain online indefinitely. (Note that the timing of the spikes is likely an artifact of the data gathering process; it would not be surprising to see equivalent spam volume on the days between the two spikes.)
The spam posts advertising Undress App are highly repetitive, with many posts duplicated dozens of times by dozens of accounts each. The exact duplication of entire posts indicates that, despite promoting a generative AI product, the posts themselves are unlikely to be produced by generative AI. Almost all of the repeated posts have three hashtags appended to the post; the hashtags are drawn randomly from a pool that includes #AI, #undressapp, #nudify, #undress, and other similar tags. Undress App spam posts comprise most or all of the recent search results for many of the hashtags tweeted by this spam network.
Unsurprisingly, some of the Undress App spam accounts have a history of posting other types of spam as well. Many of the older (and potentially hijacked) accounts have posted cryptocurrency spam or responded to cryptocurrency giveaways at some point within the last year or so. Some of the accounts, particularly the more recent creations, also repost porn. As with the Undress App spam, it is possible that more of these spam posts were present at one point but were subsequently deleted.
