You do you. But it may have an impact on people looking at your profile. As people in this thread write. But on the other hand you might also attract the attention of someone who is more on the same wavelength as you. It’s up to you to weigh the pros and cons. Do you want to fit in with the inexpressive, professional corporate tone, or do you want to add a bit of color? You can’t please everyone anyway, but it might serve your interests to conform to the expectations of people you DO want to please.
(I’d do it, even though I normally don’t use that many emojis. But I know it annoys some people way more than makes sense by any degree so that’s a good reason UwU)
Okay in relation to what?
Socially speaking, people will look at you weird.
Hygienically speaking, a bad idea as constant moisture etc. risks both bacteria and fungal infection.
If you touch things that other people touch with saliva in your hands, you might run into some trouble because again, it’s unhygienic and most people will think it gross.
If you’re cool with all that, you do you but other people don’t have to be cool with you doing that.
