In terms of warnings, then I don't believe so unless the user uses them at inconvenient places here. They will also get a warning if the use of the examples you mentioned above are shown to be distracting to users on comments and threads.

However, in a general way, if the user goes overboard with them at a singular place (such as your profile), it can cause tremendous lag.
