mask password without 3 or more recurring characters

[postak05]

Hello,

    is it possible to use mask, but exclude all passwords containing 3 or more same characters in row(case insensitive)?

Example of passwords to avoid (with marked repetition):

aaabcdefgh
qwertyyyyyy
zzyyrrrooee
qwEeE110

Example of passwords not to avoid:
qqwweerrttyy
12312312311211
aabababa


My idea is, that there's really low probability, that generated password will contain 3 or more same characters in row. Also there are (probably) no words containing 3 or more same characters in row. So we can dramatically lower the count of passwords we must check.

Thanks in advance!
