In response to the clear dictatorially of Lukashenko, many young Belarusians protested against him and his government, including Ales. However, Lukashenko cracked down on these protestors and many were imprisoned
In response to the arrests, Ales founded Viasna-96 to help support detainees and their families. As problems persisted, the organization was renamed Viasna Human Rights Centers and organized. In response to the questionable elections of 2001, Viasna protested the illegitimate elections. As a result, Viasna lost state recognition but continued to speak out for oppressed Belarusians. In 2011, Ales was imprisoned under false charges and sentenced to 4.5 years in a penal colony but served only 2 due to international outrage
In 2020, Belarus saw some of the largest protests due to another bogus election that continued Lukashenko's reign as president. The Belarusian government cracked down hard on protestors, with over 35,000 arrested. In 2021, Ales, among other notable Belarusian human rights activists, was summoned for questioning on acts of "funding of actions that grossly violate public order.” He demanded the questioning be conducted in Belarusian, causing it to be postponed. When it did happen, he answered their questions and explained why he fought for Belarusian human rights. In July of that year, Ales and several other Viasna members were arrested and charged with smuggling and remains in prison
