Abnormal tweetId in Note request data

[avalanchesiqi]

The newly released note request data is said to have four columns "userId tweetId createdAtMillis sourceLink". I notice that a non-trivial amount of tweetId seem to be abnormal.

Example:

cat batSignals-00000.tsv| grep $'\t91540'
C23DBB56A37D9566AE659462EA431791A55D9403F8E0B54E5E5899E236B9526A	9154089611629224624	1724916211485
BE177514EB62FA0F486A310A3DD07698C591ACE5077E70E5B5E9AFC105DD2DCE	9154092414728527376	1726533818655

Usually, tweetId starts with "1" but the above two tweetIds start with "9". I also searched for all requests proposed by the first userId.

It looks like all of this person's requests are on some sort of abnormal tweetIds. All of these tweets are not available on X. Is there a bug in exporting tweetIds for the note request data?

Updated: The requests with abnormal tweetIds are very small fraction---about 0.09%.
