You're temporarily restricted from liking posts, pages and comments right now. This is because there's been some unusual activity in your account
Who can help me unlock to like posts, pages please?
You could just try to write and email to facebook and wait for their answer or be patient and wait till the time of "ban" will went to zero.
Its not a proper idea for you to write or email them since you do violate their terms when it comes to spamming and its normal for a service or anywhere on the net that posting on excessive or on a short gap is considered inappropriate and its just right for them to give you the restriction. You don't have any choice but to wait up for the time limit of such ban or restriction.
Unusual activities on facebook only comes when we are posting too much of information which is not authenticated by the facebook as facebook and other social media like these are having their own rules and regulations of the relentlessly posting too much over the facebook, you can contact facebook for the problem solution or you can post in a interval of time as frequent posting can relate you on some political activities which can be violent for them, these issues will be solved in a few days and its better if you change your content as well as there are lots of scams over the market so facebook want his site to be protected from these.
They do already revert back their restriction with Crypto related post or ads and even just on usual posting stuffs they do always have rules.
