how do you deal with someone who tries to get at you indirectly on forums like this

so that person will post something knowing i'm likely to see it, they're aware of my presence on the forum, and they are posting things not directly to me, but indirect, as in what 'they' post, to wind me up...using laughing emojis with tears falling from its eyes etc...knowing it's going to wind me up? especially because i've posted on a lot of serious topics...so they're trying to wind me up about that??

i'm feeling really wound up at the moment, because i've seen a post like that before on here...someone who i think is trying to get at me in an indirect way and wind me up.
