⁸I don't know what data they have at hand to work with, the following is mainly guesswork / how I would do it:

As far as I know, US authorities have quite liberal access to data stored by US companies (due to the cloud act even if the data isn't originally stored in the US), especially in case the data is about non-citizens where some of their protection laws don't hold. Most social media accounts are tied to phone numbers and/or email addresses.

If I was in their place, I'd have a relatively small database with all (or at least all non-US) phone numbers used for social media accounts, with the email addresses tied to those accounts. If a visa-applicant applies and I get their phone number (email address),

1. I'd query a list of all accounts for that number (email) to get the associated emails (numbers).
2. With those new emails (numbers) I'd repeat step 1

If you call the office or enter your number in your application, they might get some accounts. If you associated an email address to that account, they might get additional different accounts by that email. If those different accounts have a different phone number associated to them, they use that new phone number to get more accounts. rinse, repeat.

[Edit: This process would be completely automated, of course. Not manual.]

The consequence of being caught lying might be to get your visa revoked / denied once you are already in the US at the airport, which would be highly inconvenient. Or, if they get suspicious, find something else, and get annoyed, maybe it could even be punished? I don't know.

You could maintain a separate phone with a separate phone number and separate email addresses for accounts you want to keep secret. Or maybe get a fresh phone number / email address just for the trip. But that's quite a bit of effort to maintain consistently.

1. It's not a visa but an ESTA. The visa is still granted on the fly on entry.
2. The U.S. require the same the other way around, only the one granted by the EU is $10 cheaper and valid for 3 years instead of 2, so still U.S. citizens get an advantage
3. EU citizens (like all other non-immigrants) have to, as far as I understand, disclose all their social media accounts when applying for a US visa

For VISA applications, https://travel.state.gov/content/dam/visas/Enhanced%20Vetting/CA%20-%20FAQs%20on%20Social%20Media%20Collection%20-%206-4-2019%20(v.2).pdf should apply.

What if applicants participate in multiple online platforms? Are they being asked to list all of their handles, or only one?

Applicants must provide all identifiers used for all listed platforms.

I reached that document via https://www.ustraveldocs.com/de/de-gen-faq.asp#qlistgen21 ("Apply for a U.S. Visa in Germany") and didn't find any hint for exemptions for German citizens or E U citizens, so I assume it applies. (But I might still be wrong.)

Since it's not Twitter anymore, we should replace "tweeting" by "Xcreting". (It's not mine, saw it on Reddit, but I think the idea deserves more exposure!)

Well, the activists target SUVs in the middle of Hamburg. That's not really a comparable situation. I agree it would suck if you visit a big city and get targeted there, but I would hope the activists can decide between a polished up city-only SUV and an actual working-vehicle and act accordingly.

Well, if they want to go shopping right now, chances are for this one trip they'll take their spouses smaller car, public transport or maybe even walk. If SUVs become generally unreliable (because you never know if you have air in your tires when you need it), people will look for something more reliable. They'll bitch about it, they won't act out of conviction or so, but who cares.

That is why I like this targeted actions over the gluing themselves to the road ones. This is targeted to people destroying the climate. I don't think there is any good reason to drive an SUV or a sports-car in a city, and it is actively harmful. To pick up your equivalence: Feminists fight misogyny and inconvenience those guys actively showing it without necessarily alienating average guys.

Not yet, but I already elected ultra-capitalist parties to make sure not to stop the exploitation, so I can become the exploiter eventually :-)
