the substitution rule here in the case of "thaaaaaaanks" is that it must not for any letter to be repeated more than two times
why two times because there is some words contain two letters like "success"

so in the case of somebody will write "thaaaaaanks" it should be replaced by "thaanks"

I know that it is not correct for spelling of "thaanks" but at least we reduced the shouting to its minimum limit

another example " goooooooooooooooooood " , if you will apply the rule that I gave it should be replaced by " good "

this option if you will put in your product , your product will be very very nice .

those rules should be applied to the message body and the titles as well .

best regards
