Âge du compte et nombre de tweets : deux expressions qui veulent dire autre chose en anglais

Before anything useful can be said about these two terms, they have to be separated from what they mostly mean in English, because in both cases the common meaning is not the marketplace one.

"Account age" mostly means the person's age

Search it and what comes back is age checker, age verification, age restriction, age-locked, age limit, age requirement. Almost all of that is about platform rules on how old a user is: accounts locked for appearing to be under an age threshold, content restricted by age, verification processes for proving age.

The other sense, how long ago an account was registered, barely appears. "Aged twitter account" as a phrase returns no suggestions at all.

If you arrived here from a search and your problem is an age-locked account, none of what follows applies to you. That is a verification process with the platform, not a property of an account you might buy.

"Tweet count" mostly means a counting tool

Same pattern. The suggestions are tweet counter, post count, character count, word count, calculator, cooldown, and notably "post count wrong", which is people whose displayed number does not match what they expect.

None of that is "how many posts an account has as an indicator of use". That reading exists, but it is a marketplace convention rather than a common English usage, which is worth knowing if you are searching for guidance and finding tools instead.

Now the actual question: what are these signals worth

Three properties get discussed together and they behave completely differently, so it is worth taking them apart.

Registration date: priced, and priced as a step

This is the only one of the three that the market prices, and it does so sharply. Accounts registered before 2022 cost roughly twice the middle price, in two bands that cost the same as each other, and accounts from 2022 onward sit slightly below the middle. So it is a cliff at 2021 rather than a gradient, and a 2015 account is not priced above a 2019 one.

What it signals is narrow but real: the account existed before a particular period. It does not signal that anything happened during those years.

Posting history: not priced directly, and the distribution matters more than the number

There is no posting-count attribute in the pricing. The nearest thing is a filled profile, at about a third of listings and half again the middle price.

Where history does matter is to a human looking at the profile, and there the shape matters more than the total. Twenty posts spread across several months reads differently from twenty posts made in one afternoon, even though the number is identical. If you are buying for something a person will look at, that distribution is worth checking with your eyes rather than filtering for with a number.

Followers: not priced at all

There is no follower attribute anywhere in this shelf's pricing, which is striking given how much of the English demand asks for one. Where a listing states a count, that is free text from the seller, so it is something to verify in the first minutes rather than shop on.

And it is only worth anything for one kind of use. If the account will feed a tool, followers change nothing and paying for them is waste.

What the three together can and cannot tell you

Combined, they make a profile look like one somebody has been using. That is genuinely worth something when a human will look at it: a partner, a customer, an audience.

They do not tell you the account has better standing with the platform, that it will not be rate-limited or asked to verify, that its history is continuous and genuine, or anything at all about what happens after you start using it. Those are not things that any listing attribute measures, and a listing implying otherwise is describing something it cannot see.

Deciding what to pay for

• A human will look at the profile. Registration tier and a filled profile both earn their premium. Check the posting distribution yourself once you have access.
• A tool will use it. None of the three matters. Buy on format and warranty terms and take the cheapest tier, which is the post-2022 one, sitting below the middle price.
• Somebody else will take it over. What matters is a complete handover, meaning the second factor and recovery mailbox, not the appearance of history.

The registration tiers and profile tags are filterable on the X accounts shelf, and the buying guide covers what else moves the price.
