I would ask label lovers to pay attention to a small detail: the label must be typed directly next to the hashtag symbol.
Like this: #etichetta
Typing it incorrectly, that is, separated from the hashtag symbol, creates a label with just the symbol.
Like this: #
This causes a notification to go out to all users who made the same mistake in typing the label, and I am fully convinced that these people receive enough notifications without your contribution.
And then the label itself is useless if typed incorrectly. #etichettatenelmodogiustochericevo unacarrettadinotifichediobubu
