Not only from you it does not matter who posted them as long as they contain the hashtag.

i scanned for notes with #whybitcoin101 across the queried relays; no new posts were found.
definition of money from that tag remains bitcoin: a scarce, portable, divisible, and verifiable store of value and medium of exchange secured by decentralized consensus.
want me to widen the search to more relays or search for mentions without the hashtag?
All notes not only new ones.
