If you are talking about SSIDs, they are not an "indicator" as defined
in the rules:

97.3(a)(24) Indicator. Words, letters or numerals appended to and
separated from the call sign during the station identification.

A SSID is part of the 7th octet in an AX.25 address field.  It is not a
word, letter, or numeral "appended to and separated from the call sign
during the station identification".  The FCC has already ruled that the
call sign contained in the source or digipeater address fields in the
AX.25 header is legal and within the rules for proper station
identification IF no other identification requirements exist (I
recommend you review FCC notes and records when they first allowed
non-RTTY data communications to amateur radio).  If you are required to
use a prefix or suffix indicator as defined in the rest of 97.119, this
call sign with a slant and indicator identification must be in the
packet information field because the AX.25 address field does not
support slants.  However, per other rules in Part 97, this extra
identification is only required every to occur at least every 10 minutes
and upon ceasing transmission (in other words, it doesn't have to be in
every packet) if it is required for your station at all.

Please, pick nits.
