Banned but still have acces

[محروم.كوم]

Hi,

I've banned two users, but they still visit the forum every day and show up in the list of users who visited the forum today.

I've banned all their IP adresses that I could find, but in the list of users who were on the forum, one of those IP adresses still shows.
So I banned an IP adress and this IP adress is used to visit the forum?

How is this possible? __DEFINE_LIKE_SHARE__
